If you like stair lighting as much as I do you will want to have a look at this. Geert built his RGB Stair Lighting using an Arduino Uno and TI TLC5940m PWM Chips. He uses 3 of the TI TLC5940m chips to allow to control 3 channels of light on each of his 12 stair steps. Geert now has some cool lights on his stairs and his next step is to add a detection method to activate them automatically. If you don’t have the time to build your own but still want the stair bling, have a look at this stair lighting controller or this stair lighting kit.
