Huge Comercial RGB Stair Lighting Installation – Cost No Option


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.


DIY Strip Light Stair Lighting Design and Install


This DIY Strip Light Stair Lighting Design and Install over at Speedy Signals looks nice. The project uses a ATmega328P which is very common in the Arduino scene. The microcontroller interfaces with some shift registers to power the lights. Some 2N7000 mosfets are used to drive the actual LED lights. By using the Arduino ShiftPWM library he is able to have individual control of all the steps. Beam sensors were the first idea but motion sensors were eventually used.




Automatic Motion Detection Stair Lighting

Titan Homes is adding some cool stair lighting to some of their custom homes. Check out the video of the Reactive Lighting stair lighting system they install for their lucky customers. Austin demonstrates how the stair lighting controller can easily be configured by just flipping a few switches. A few of the many lighting sequences are demonstrated by using the random mode which looks like a lot of fun! They have mounted the controller out of the way under the stairs so it can accessed if needed. I am sure the new homeowners will have a ton of fun each time they use the stairs. I wonder how many of their neighbors will be getting their own system in the coming months. 🙂



RGB LED DIY Stair Lighting using an Arduino Uno and TLC5940 chips

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 lot of PWM controllers. With 12 steps, 3 colours per step, we need 36 PWM channels. My Arduino Uno only has 6 of them, so that’s not an option. Texas Intruments has a solution: TLC5940, a 16 channel PWM unit with 12 bit duty cycle control. It has a serial input, and can be daisy chained to create even more channels. In this case, I need 3. Luckily there is a library for this chip in the  Arduino Playground”
