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 Arduino project demonstrates how to use a potentiometer as an analog input to control the brightness of an LED using PWM (Pulse Width Modulation). The analog input is read from pin A0, scaled to ...

I cannot get over how easy it is to get code running on an Arduino, allowing me to write the code to try to connect to a 20 character x 4 line LCD (wearing an I2C-to-parallel ‘backpack). Update: Part3 ...
