Overview This project demonstrates how to control the brightness of an LED using a potentiometer (analog sensor) with an Arduino. The potentiometer’s value is read by the Arduino and mapped to control ...

This project aims to experiment with the digital control of a digital potentiometer type M62429 and an RGB LED ring. This is done by an Arduino Nano, which reads a Rotary Encoder. The position of the ...

We set the potentiometer pin as 0 (A0 on the Arduino Uno board), the CONTROL variable is the voltage that is used to cotrol the led brightness of the speed of the fan. In the setup() function the ...
