This repository contains an Arduino script that demonstrates the usage of potentiometers to control LEDs. The script reads the voltage produced by a potentiometer and lights up corresponding LEDs ...

Analog Input. PWM Output. Full Control. Fourth step in the embedded grind. This isn’t just about lighting up LEDs—it’s about using analog input to shape digital output. 3 LEDs. 1 potentiometer.

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 ...
