3LED Dimmer Switch
In this project, you’ll build a light dimmer by controlling the brightness of an LED using a potentiometer. The power in this project lies in your ability to read analog inputs with the Raspberry Pi and output pulse-width modulation signals. These will be incredibly useful skills in future projects and in your Pi learning.
