Today, many people love to keep cats as pets, but they are busy with work and do not have time to feed their cats. This initiative was born based on several existing cat feeder studies and the health of the cat. Sometime, many cats do not eat according to their needs, which can be seen in their body composition, such as being fat or skinny. The main purpose of this research is to provide a cat feeder product that can automatically provide food for the cat when it is time to eat and give the same amount of food to the cat every day. This project combines a few components such as an Arduino UNO as a microcontroller, a keypad as an input, a Liquid Crystal Display (LCD) and a servomotor as an output. This project also uses RTC module DS3231 to display the time on the LCD in sync with real time. This project starts with the user pressing the button and then the user needs to set the feeding time using the keypad. Once the set time is reached, the motor will rotate from 0 to 90 degrees and the food will drop into the bowl. As a result, the cat feeder is fully functional and achieves its objectives. According to the findings of the study, the automatic cat feeder helps users resolve the issues mentioned above. Keywords: Arduino UNO, RTC, keypad, LCD, Cat Feeder, Servo Motor INTRODUCTION Todays, most people choose to keep cat as their pet and often as a companion. A cat is a good companion for a human as it eases the strain of daily life and acts as a deterrent to burglars. Nowadays, people consider cats to be members of the family. In order to maintain a cat's health, a balanced diet must be taken into account, varying depending on the size of the cat. According to the surveys, cat owners' busy schedules are to blame for the obesity issue in LI animals [1]. Any pet requires care, and the owner must be present to provide it. Some animals lack the ability to restrain their appetites and will eat continuously eat if there is food available. Problems can occur when the owner must leave their pet for an extended period of time and there is no one available to take care of it [2]. The design of an automated cat feeder was developed to assist cat owners and to combat the obesity and starvation issues. It utilizes components such as Arduino, a keypad, an LCD and a servo motor [3]. This project involves programming the Arduino to control the feeding mechanism. The code specifies the duration of the motor should rotate and declare the connection of pin between Arduino and other components. Additionally, an RTC DS3231 module is employed in this project to synchronize the time based on real time data. A keypad is used to input the feeding time [4], which is the displayed on the LCD screen. Lastly, the motor is responsible for turning the lid of the food jar. METHODOLOGY Figure 1 shows a block diagram consisting of the keypad as the input to set the feeding time. Arduino Uno as the microcontroller that has 6 analogue inputs, a 16 MHz quartz crystal, a USB port, 14 digital input/output pins, a power jack, and 14 input/output pins for digital data. In this project, Arduino is used to receive signals from input and send them to the output which is an LCD and a servomotor. These are the main components used in this project.

Block diagram of the automatic cat feeder RESULT AND DISCUSSION The system starts when the user presses a button, which send signal in the form of digits 0 and 1 to the Arduino. Once the Arduino receives this signal, it sends it to the LCD, which prompts the user to set feeding time using the keypad. The signal from the keypad is send to the Arduino and then send to LCD and servomotor. When the set time matches the real-time, the servomotor will spin from 0 degrees to 90 degrees and turn back into its original position after a 1-second delay. If not, the servomotor will remain in the same position. Lastly, after the first spin, the food for the cat will drop into the bowl. Figure 2 illustrates the prototype of automatic cat feeder and LCD display real time and date. The overall process of the automatic cat feeder is shown in Table 1. Figure 2.

Ghani1 1 School of Electrical Engineering, College of Engineering, Universiti Teknologi MARA Cawangan Terengganu Kampus Dungun, 23000 Dungun, Terengganu [email protected], [email protected] Abstract: This project presents an automated clothesline that protects clothes from rain and exposes them to sunlight. The clothesline uses a WEMOS D1 R1 development board, a rain sensor, a light-dependent resistor (LDR), and DC motor. The rain sensor detects rain and sends a signal to the board, which then closes the roof of the clothesline. The LDR detects sunlight and sends a signal to the board, which then opens the roof of the clothesline. The clothesline can also be monitored remotely using the internet of things (IoT). Using this automated clothesline was able to reduce the risk of clothes getting wet. Keywords: rain, WEMOS D1 R1, light-dependent resistor (LDR), clothesline, IoT. INTRODUCTION The weather in our country is unpredictable and can change from sunny to rainy in a matter of hours. This can make it difficult to dry clothes outdoors, as they may get wet if it rains. Additionally, many people are busy with their careers and other commitments and may not have time to hang their clothes outside. This can lead to clothes becoming damp and smelly. Bacteria and other germs will be trapped in the material of the clothes and can be spread throughout the body if people wear wet clothing. If you wear wet clothes, you may develop a rash or itchiness. The presence of these bacteria can lead to an increase in infections if a person wears wet clothing in an area with poor ventilation [1]. The Automatic Outdoor Clothes Hanger Rack is a solution to these problems. It is a smart, IoT-enabled clothesline that can automatically retract and extend depending on the weather. This means that clothes will never get wet in the rain and will always be exposed to the sun when it is dry. Additionally, the clothesline can be controlled remotely, so users can always be sure that their clothes are drying properly. METHODOLOGY Figure 1 shows the block diagram of the system. The light dependent (LDR) sensor water sensor detects sunlight and rainfall, respectively. The Blynk application sends a notification when either sensor detects a change in condition. The WEMOS D1 R1 sends the data to the DC motor, which opens and closes the clothesline. The Blynk application also displays the values from the input sensors, as well as the weather condition.

For the LDR sensor if the value is higher than 500 shows that the weather is clear and if the value is lower than 400 shows the weather is cloudy. When both sensors show combination of value = 0 for the water sensor and value lower than 500 for the LDR, the DC motors will retract the clothesline. Owners that are maybe still working can feel secure that all the laundry is mostly dried since they can monitor remotely the status of their laundry via the Internet of Things (IoT). Table 1: Sensor input value Water Sensor Value LDR Sensor Value 1 or 0 0 - 1023 CONCLUSIONS Overall, the automated system presented in this project is an acceptable option for exposing clothes to sunlight and protecting them from rain. This system utilizes a combination of sensors and actuators to automatically control the opening and closing of the clothesline, and it can also be monitored remotely using the Internet of Things (IoT).

However, for individuals who do not have free time and are not close to plants due to work, it is very difficult to commit to taking care of plants. This paper is about the Automatic Plan Watering System that uses a microcontroller application to control the crop irrigation process. This automatic control process uses several types of sensors such as soil moisture sensors and water level sensors to control the operation of the water pump. The results of the development of this project show the difference in plant growth using the proposed automatic system and the manual method. Keywords: Plant Watering System, Soil Moisture. INTRODUCTION This paper is about the development of an Automatic Plant Watering System that is used specifically for ornamental plants. Gardening is one of the healthy hobbies that can relieve stress. However, for individuals who live in cities or in high-rise houses, this hobby is difficult to do because of the low level of existence at home. A few researchers came out with the application of fuzzy logic-based water pump trigger to irrigate the plant [1]. However, the complexity of the system might not be suitable for ornamental plants. Some of the researchers also highlighted on the availability and the optimizing the water usage for irrigation to avoid water waste [2], [3].Therefore, this system was developed so that the planting and maintenance of ornamental trees can continue by ensuring that the plant medium is always moist. This system uses an electric pump to irrigate the plants. This electric pump will be controlled by the microcontroller when it receives information from the soil moisture sensor and the water level sensor in the tank. When the soil moisture sensor reads the soil moisture below 55%, the microcontroller will turn on the electric pump to flow water to the plants using the drip method. The water level sensor will ensure that the pump will not be turned on when the water level in the tank is too low in addition to showing the low water level reading on the LCD screen. METHODOLOGY The development of Automatic Plant Watering uses an Arduino UNO as a microcontroller that is connected to two sensors, namely the soil moisture sensor and the water level sensor in the tank. The microcontroller will analyze the sensor readings and perform a comparison with the minimum soil moisture level set at 55%. Figure 1 shows the block diagram of the Automatic Plant Watering System.

Electrical Engineering Innovation, Competition & Exhibition 2023 (EEICE 2023) e-ISSN 2682-7565 Vol. 2 Online : June 2023 9 Based on Figure 1, it can be seen that the readings of the sensors, the microcontroller will display the water level readings and soil moisture values to the user. To classify the level of soil moisture. Several classifications have been made based on soil moisture ranges. While the classification of the water level in the tank is based on the sensitivity of the water sensor that has been attached to three levels of the depth of the tank. RESULT AND DISCUSSION Table 1 shows the classification of soil moisture and water level displayed on the 16x2 LCD screen. The microcontroller was programmed to distinguish three conditions of soil moisture and water level as shown in Table 1. To maintain the moisture level in the plant medium, the DC water pump was set to run when the reading of the soil moisture level falls below 55%. However, the increment of soil moisture level will take some time due to the slow water flow rate into the plant medium. Table 1: Classification of soil moisture and water level sensor displayed on LCD screen. Sensor’s type Reading, Information displayed on the LCD and classifications Soil moisture sensor 0% - 30% 31% – 70% 71% - 100% Dry soil Moist Soil Soggy Soil Water level sensor < 20 cm 20 cm to 35 cm >35 cm Low Medium Full CONCLUSIONS The Automatic Plant Watering System shows a working concept of automation that could help people with the hobby of planting ornamental plants to continue their hobby. The system use a simple and modern device to govern the watering process of ornamental plant. REFERENCES [1] M. S. Munir, I. S. Bajwa, and S. M.

Electrical Engineering Innovation, Competition & Exhibition 2023 (EEICE 2023) e-ISSN 2682-7565 Vol. 2 Online : June 2023 10 AUTOMATIC RAINWATER SENSING UMBRELLA USING ARDUINO MICROCONTROLLER Adryana Atiqah Syahrul Erman1 , Siti Aishah Che Kar1 , Rosmawati Shafie1 1 School of Electrical Engineering, College of Engineering, Universiti Teknologi MARA, Cawangan Terengganu 23000 Dungun [email protected] Abstract: Automatic rain-sensing umbrella is created to protect open stall selling goods from rain by using a rain sensor that senses the presence of rainwater. Even though market sellers would use a canopy tent to run their business, but a tiny splash of rainwater can be caught in the selling goods. The system would sense raindrops and immediately turn on the motor that is attached to the pinion rack to open the extended umbrella. When there is no raindrop sensed, the motor will spin in another direction to close the umbrella. The system has a programmable device Arduino which will help in controlling stepper motor for opening and closing the umbrella and two switches aiding for better control in all direction. The umbrella can be controlled by using a mobile device (preferably smartphones) that installed a specific app and connected to the system’s Wi-Fi. Sellers are able to control the umbrella through their devices; open and close umbrella manually. Keywords: Automatic, Rainwater Sensor, microcontroller, Arduino. INTRODUCTION Extreme weather events and increasingly unpredictable weather patterns are observed on a global scale. The purpose is to design an automatic umbrella system that can open and close by using Arduino programming. It can be helpful to not only save the life of cloth, street vegetable the vegetables, fruits but in some situations also save the human life. There are previous automatic design papers explanation based on microcontroller that can detect the rainwater in domestic application such as automatic rooftop, cloth line and automatic shed system [1-4]. For this project, it is specifically created to ease open stall market sellers when running their business in an open space. Open stall market sellers are one of the most exposed to weather when working or running their business. So, the automatic umbrella can help them to face fewer problems such as putting up tarpaulins when it starts to rain. The automatic umbrella system will detect rain fall onto it and trigger the system to turn on the motor to spin the gear and pinion attached to the umbrella. METHODOLOGY The rain sensor and access monitoring system are made up for automatic rain sensing umbrella. IFTTT application is used as a medium to receive information of the umbrella condition; open or close. The rain sensor is the main input of the system where the sensor system is connected to the Wi-Fi module (ESP 32). The system used other component such as Arduino UNO, motor, Atmega328 microcontroller, servo motor, stepper motor, capacitor, resistor and transistor. Each component provides their specific function in order to achieve the objectives of this project

Electrical Engineering Innovation, Competition & Exhibition 2023 (EEICE 2023) e-ISSN 2682-7565 Vol. 2 Online : June 2023 13 DESIGN AND DEVELOPMENT OF DIGITAL SAFE BOX USING ARDUINO Ahmad Haziq Kama1 , Rosmawati Shafie1 , Norizan Ahmed1 , Rina Abdullah1 , Siti Aishah Che Kar1 1 School of Electrical Engineering, College of Engineering Universiti Teknologi MARA, Cawangan Terengganu [email protected] Abstract: This project presents the design and development of digital safe box using Arduino. A safe box serves as a medium for storing valuable items and protects them from burglars. This safe box is created to provide maximum burglary protection which improves home security. The initiative is based on the difficulty of finding a suitable location to hide and store valuable items. An Arduino UNO is used as a microcontroller to control the servo motor and Liquid Crystal Display (LCD). A 4x4 keypad is used for input entry and displayed the number on the LCD. If the code entered matches the stored code, the Arduino sends a signal to the servo motor which rotates by 90 degrees to unlock the safe box. The implementation of this technology provides an alternative to traditional key locks and can be modified to include additional security features such as biometric identification. Keywords: Arduino UNO, safebox, password, keypad, LCD, servo motor INTRODUCTION Home safety and security encompass the implementation of various measures to protect a residence and its occupants from risks, dangers, and intrusions, with the aim of minimizing accidents, theft, vandalism, and harm to individuals within the household. Theft, which involves the unlawful acquisition of someone else's property without consent, is a significant concern in relation to home safety. In fact, it has been observed to be the most common type of property crime in Malaysia [1]. The growing concern for security and protection against theft and unforeseen events highlights the need for a reliable storage solution to safeguard valuable possessions like important documents, jewellery, cash, electronic devices, and other valuable items within our homes. In response to this need, a digital safe box has been developed as an effective solution, providing an additional layer of protection, and serving as a secure storage solution to mitigate the risk of theft or loss. Earlier studies have effectively showcased the development of projects focused on enhancing home safety and security [2]–[4]. For instance, Yahya et al. demonstrated an automated safety box that incorporated a fingerprint and password input system, controlled by the Arduino UNO [5]. Motivated by the findings of previous research, this study proposes a digital safe box as a solution to address the increasing demand for enhanced home safety and security measures. The proposed digital safe box serves as a demonstration of the potential of Arduino technology in developing an advanced and secure storage solution, effectively ensuring the protection and confidentiality of valuable belongings within residential settings. The Arduino UNO acts as the central control unit, enabling the integration and coordination of various components to create a functional and reliable safety box system. The Micro servo motor facilitates the locking and unlocking mechanism, ensuring secure access to the box's contents, while the 4x4 keypad provides user-friendly input for password authentication. Additionally, the 12C LCD display allows for informative feedback and system status updates, enhancing the overall user experience and interaction with the safe box.

Block diagram Figure 1 shows a block diagram of the overall process for designing and developing a digital safe box using Arduino. This project uses the Arduino UNO as the main controller to control the entire process, starting with the insertion of a 6-pin via a 4X4 keypad input, followed by the display of the password status on a 12C LCD screen, and ending with the activation of a servo motor actuator. When the user inserts the correct 6-pin on the keypad, the Arduino Uno sends a signal to the LCD display to indicate whether the password is valid or not. The motor will turn 90 degrees and open the door box simultaneously if the password is correct. After five seconds, the motor will return back to its original position to ensure proper operation of the safety box door. RESULT AND DISCUSSION Figure 2. (a) PCB board testing. (b) and (c) Final Digital Safe Box installation prototype. The important part after the simulation circuit design is the PCB board testing. Before the hardware installation process, the PCB board testing as shown in Figure 2 (a) is required to ensure that the circuit works properly. The result during PCB board testing, the first status "Enter Password" was seen on the 12C LCD display. The hardware experiment demonstrates that when a 6 pin is successfully insert from the 4x4 keypad, it will display on the LCD screen. It allows the user to validate the password, and the servo motor will rotate 90 degrees to unlock the door and then after for 5 seconds the servo motor will be returning to its original position to lock the door for safety purpose as shown in Figure 2 (a) and (b). 4 x 4 Keypad Arduino Uno Servo motor LCD Display
Electrical Engineering Innovation, Competition & Exhibition 2023 (EEICE 2023) e-ISSN 2682-7565 Vol. 2 Online : June 2023 15 CONCLUSIONS Safe box is a type of security box and an artificial intelligence system that provides humans with secure, convenient storage for important items such as documents, money and other valuable items. Contrary to believe, this safe box cannot be opened without a password. The keypad provides secure access to the safe box while the Arduino microcontroller ensures that the safe box operates seamlessly. The servo motor and LCD provide visual feedback and display of information respectively. The safe box is almost impossible to open without the owner’s password, making it secure against theft and reducing crime in the country. It also protects important documents such as passports and social security cards from burglary or natural disaster. However, additional security features such as biometric scanners or facial recognition technology are recommended to ensure utmost security of the safe box. REFERENCES [1] M.

Electrical Engineering Innovation, Competition & Exhibition 2023 (EEICE 2023) e-ISSN 2682-7565 Vol. 2 Online : June 2023 19 AUTOMATIC FAN AND LAMP FOR PRAYER ROOM Muhammad Tariq Bin Hermain1 , Wan Ahmad Khusairi Bin Wan Chek1 1 School of Electrical Engineering, College of Engineering Universiti Teknologi MARA, Cawangan Terengganu [email protected], [email protected] Abstract: People sometimes forgot to switch off the fan and lamp after they enter a prayer hall to perform prayer. To overcome this problem, this paper proposed an automatic system that can control the ON/OFF of the lamp and also the fan. PIR sensors are used to control the ON/OFF for both lamp and the fan. A temperature sensor DHT11 is used to detect the temperature of the room. All the input and output are connected to the Arduino Uno microcontroller. In this project, the goal is to avoid wasting electricity done by people who use the prayer place and forget to turn off the light switch and fan after the prayer room is used. Keywords: PIR sensors, automatic, DHT11 sensor, Arduino UNO. INTRODUCTION To conserve energy and reduce utility costs, it is necessary to turn off the lights when leaving a room or other area where lighting is not required. Turning off lights when not in use can help you save money by lowering your electricity bill and extending the life of your light bulbs, reducing the frequency with which you have to replace them [1]. The objective of the project is to conserve energy by turning off the lights and fans in the prayer room when they are not in use. This can be achieved by installing a PIR sensor that detects when people enter the room. METHODOLOGY Figure 1 shows a block diagram of the project. The PIR motion sensor detects motion in the room by detecting changes in infrared radiation. When the sensor detects motion, it sends a signal to the Arduino. The Arduino then activates the AC fan and the LED bulb. The AC fan will help to cool the room, while the LED lamp will provide light. The temperature sensor detects the temperature in the room. When the temperature exceeds a desired temperature, the sensor sends a signal to the Arduino. The Arduino then sends a signal to an LED indicator. The LED indicator will turn red if the temperature exceeds or equals 28.0 degrees Celsius and green if the temperature is below or equal to 27.5 degrees Celsius.

If there is no human movement detected, the LED lamp and AC fan will turn off. Figure 3 shows the condition of AC fan and LED lamp if motion is detected. If there is human motion detected, the LED lamp and the AC fan will turn on. The results of the experiment show that the PIR sensor was able to successfully detect human motion and control the switching of the lamp and fan accordingly. When there was no human motion detected, the lamp and fan were turned off. When human motion was detected, the lamp and fan were turned on. CONCLUSIONS In conclusion, this paper proposed an automatic system that can control the ON/OFF of the lamp and fan in a prayer hall. The system uses PIR sensors to detect the presence of people in the room and a temperature sensor to detect the temperature of the room. When no people are detected in the room and the temperature is below a certain threshold, the system turns off the lamp and fan. This system can help to avoid wasting electricity by people that forgets to turn off the lights and fan after using the prayer hall.

Electrical Engineering Innovation, Competition & Exhibition 2023 (EEICE 2023) e-ISSN 2682-7565 Vol. 2 Online : June 2023 21 HOMESTAY KEY LOCKER SYSTEM Wan Fatima Azzahrah Wan Razak1 , Mohd Saiful Najib Ismail @ Marzuki1 , Wan Ahmad Khusairi Wan Chek1 , Ahmad Izzat Mod Arifin1 1 School of Electrical Engineering, College of Engineering Universiti Teknologi MARA, Cawangan Terengganu [email protected] Abstract: Today's society places importance on security, as well as homestays. Some homestays keep their keys somewhere safe, but this is still risky because it could allow a burglar to use the key to get inside the house, such as under the door mat and vase. Another issue is that someone needs to be there every time the keys are handed over or picked up. In this study, the GSM module, and ESP 32 are used. The Arduino has previously stored the instructions from the Blynk App. The GSM module will connect to WiFi to provide the device with an internet connection, allowing the Blynk app to access the project. The locker needs access to open and close, and the LCD will help the user with the instructions. Since security is important in our society and affects almost every area, the goal of this research is to deliver good security at a reasonable cost. These lockers also help prevent burglary and are able to maintain the safety of customers' belongings and assets in the homestay. Keywords: Blynk App, Arduino, GSM, ESP 32 INTRODUCTION A homestay is, very simply, part of someone’s home converted into a hotel [1]. A homestay is similar in concept to that of a bed and breakfast. Guests are either accommodated in the family home or in separate quarters nearby. In terms of holiday homestay bookings, this may be someone’s home, or a second home, that the owner has added to a homestay website to make money by renting out their extra room, entire apartment, the whole physical house, or even their beautiful chalet. People sign their apartments up for homestay rental for a variety of reasons. Mostly, it’s to make supplemental income on an otherwise vacant space. Nowadays, most homestays provide their guests with just as much comfort as a reputable hotel. In Homestay provides a lot of assets and furniture for the customer's comfort. When customers enter the homestay, most of them forget about safety because they are tired of shopping or going for a stroll, making them the most likely homestay to be easily broken into due to customer negligence [2]. Here, the Homestay Key Locker System is a type of control access system that controls the opening and closing of the key locker to allow the customer to get the key to enter the homestay. It is a system that is implemented in a locker to keep the people and assets in the building safe from outsiders. This key locker system only assists those who have the ability to open the locker [3,4]. METHODOLOGY In the beginning, the homestay’s owner will select the ‘Unlock’ button in the Blynk App. After that, the locker will unlock and the LCD will display “Door Open,” and the buzzer will beep to notify the customer that the door is unlocked. After the customer takes or puts back the key in the locker, they will notify the owner to lock back the locker. Then the owner will select the button ‘Lock’ in the Blynk App, and the locker will lock back. After that, the LCD will display “Door Open” with a buzzer beep.
