What is an Arduino ?



Microcontroller
Microprocessor













Microcontroller or Microprocessor

What is the difference

A Microprocessor is an IC which has only the Central
Processing Unit (CPU) inside them.

They only have processing powers.
Don’t have ROM, RAM and other peripheral on the

chip.
A system designer has to add them externally to

make them functional.

Microcontroller or Microprocessor

What is the difference

A microcontroller is an entire computer manufactured
on a single chip.

It is a device that includes microprocessor, memory
and input/output devices on a single chip.

designed to perform specific tasks

Arduino Analog Input

Image credit: Tod Kurt

 Resolution: the number of different voltage levels (i.e., states) used to
discretize an input signal

 Resolution values range from 256 states (8 bits) to 4,294,967,296 states
(32 bits)

 The Arduino uses 1024 states (10 bits)
 Smallest measurable voltage change is 5V/1024 or 4.8 mV
 Maximum sample rate is 10,000 times a second

Analog Output

• Can a digital devise produce analog
output?

Image from Theory and Practice of Tangible User Interfaces at UC Berkley

• Analog output can be simulated using

pulse width modulation (PWM)

PMW Pins

• Command:
analogWrite(pin,value)

• value is duty cycle:
between 0 (always off)
and 255 (always on)

• Examples:
analogWrite(9, 128)
for a 50% duty cycle

analogWrite(11, 64)

Image from Theory and Practice of Tangible User Interfaces at UC Berklefyor a 25% duty cycle
