Automated stair lighting project

Article By : Nicolas Rabault

Creating lighting for an 11-step staircase with a lower level that turns on and off automatically.

For poorly illuminated stairs to a lower level, I wanted to create automated lighting that would add a ‘wow’ factor and be fun and very different.

Yes, of course, it would have been possible for some sort of normal overhead lighting controlled by a switch, but that requires someone to do something (simple enough, I know, to flip a switch) but it’s boring. I wanted something different. Admittedly, my project is overkill but fun and presented a number of challenges.

So, first, let’s review the project specs.

• Lighting for an 11-step staircase leading to the lower level that turns on and off automatically

• ‘Wow’ factor that would make people realize a very different and fun experience

The challenges were:

• How to make the lights come on and off automatically using some sort of sensory input

• Not altering the structure of the staircase

• Not having to invent a new system for every step while having each step perform as part of an overall system

• Having the ability to make changes, updates and perform maintenance easily on the overall system–and not 11 times for each step

My solution involved a staircase illuminated with LEDs, a sensor at each step connected to an independent board with all the boards connected and communicating with each other to form the system.

The result is:

• Each step is independent but can interact with others

• Easy updates to the systems

• Ability to change lights or add something new with no changes to the existing boards

• System can be managed from any computer to make changes, updates, perform maintenance

Here is a short video demonstration of the project:
