Analog Signal
What is Analog Signal?
Analog Signal is a continuous signal. It is different from the discrete digital signal. Analog signal are use for electronic system, mechanical, hydraulic, and other system.
Arduino board specifications (in this case use Arduino Uno Board):
- Read analog value from 0-5V.
- 10-bit resolution (0-1023)
- Readable resolution 5V/1024 = 0.0049V (4.9mV)
- It takes about 100 microseconds / 1 time
In this article, you will lean how to use Arduino boards to read analog signals. Using the Arduino board to read the analog signal from potentiometer.

Example Program
After uploading the program onto the Arduino board, see the results of running the program from Serial Monitor or Serial Plotter.
