LED Display Controller using an Atmel Microcontroller
The display case light controller controls the brightness of an LED (or any other light) using a ATMega328P and a ATtiny13A. The controller sports an on-off switch to control the state of the display as well as three push buttons to select the colour you wish to display (from a combination of red, green and blue).
The LCD Display shows the brightness of the colours, as well as the on/off state.
