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 shield is for the Arduino uno and has 6 potentiometer on every analog pin. The shield can also hold 14 servos (one for every digital pin). There are also 2 buttons on the inturuptet pins 2 and 3.

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...
