Grobenn25 built an interactive LED handrail system using an Arduino that monitors a large array of infrared sensors to detect what step the user is on. Based on the current detection pattern the stairs will light the LEDs under the handrail appropriately. During the production he looked at many different types of systems and settled on this overkill system. The sensors are changing their detection parameters constantly so that
If you have an unlimited budget this stair lighting system by Calum Gregge is amazing. Using RGB LEDs on this system combined with some creative light sequencing sure does look impressive.
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
 Fiberopticlight presents an amazing step lights created using Poly Optics Super Side Light fibre lit with LEDs at each end. Each strip of stairs consists of a single LED at each end of a 7mm Super Side Light fibre strip encased in a 10mm square polycarbonate extrusion. Entire system of strip lights is typically operated by just a single 9V power supply and the current consumption of each strip light is about
