This research is a design and building of a parabolic dish for the solar collector.
The researchers created it to accumulate heat and generate electricity by
Thermoelectric from 9.00 A.M. to 3.00 P.M. We did experiments to measure the
light intensity, temperature, voltage, and electric current. The result of the average
measurement showed the time was from 12.30 A.M. to 1.00 P.M. That one has
the greatest light intensity, temperature, and voltage. The most average light
intensity was 975.3 W/m2, the greatest average temperature was 86.7 °C and the
largest average voltage was 68.2 mV. Even so, the greatest average electric
current as 8.8 mA. We found at a different time between 11.00 A.M. to 11.30
P.M. The conclusion of this study is the position to install the thermoelectric
generator. That is the focus of a parabolic dish which can generate most electricity
in time’s interval of 12.00 A.M. to 12.30 P.M.

The aim of this project is to study the principle of the atomic force microscope
(AFM) investigated surface roughness using a flex sensor and an Arduino
microcontroller. The resistance of the flex sensor is touched on the test sample
formed by 3D printing will be changed by the roughness of the sample. Then
Arduino microcontroller will record data of changed resistance at the various
position. After that, these roughness data will be plotted by using Microsoft Excel.
The results have shown that the resolution of our demonstrated AFM is 2 mm ± 1
mm. The maximum dimension of our demonstrated AFM that can measure is 15
cm × 15 cm × 10 mm. Furthermore, this demonstrated AFM might be useful in
education.

In this project, we propose an investigation of hot air ventilation in the room,
which is scaled down to 1 3, using two zx-thermistor modules and an Arduino
microcontroller. A downsizing room is assembled by acrylic plates attached to
two ventilators at the walls. These two fans are each other attached to the opposite
side of the walls. There are two conditions of ventilated direction in our
experiment. First, the airflow from outside into the room and the other one is air
flowed from the room to the outside. Incandescence light bulbs, which use to heat
temperature, have been set up in our small model's room. In our experiment, the
temperature inside the room of two conditions has been measured versus times
and recorded by the Arduino microcontroller. The results shown that the
temperature inside the room of the first condition (the air flowed into the room)
has a higher temperature than the second condition (the air flowed to outside the
room). In the future, our investigation could be applied to agriculture (food
preservation, egg incubation, livestock project, etc)
