RGB LED DIY Stair Lighting using an Arduino Uno and TLC5940 chips
Mike Szczys from Hack a Day shares a hack that he found by Geert on his Just a Thought blog. Geert wanted to jazz up his stairs but adding some DIY RGB LED stair lighting. He used an Arduino Uno for the brain and some TI TLC5940 chips to do the heavy lifting of doing the PWM (pulse width modulation) for all of the channels of LEDs. “We need a
