First stairs

After seeing several commercial stairway lighting systems, I decided to try WLED on a set of steps. Below are the key components, all from Amazon. The aluminum track is extra deep and the cap is a rounded dome both provide depth to avoid seeing individual LEDs, but rather a uniform glow. The width and depth of the track allows running power wires along side of the LED strip.

There is no power near the bottom of the steps, so under the stairs there is an outlet. Near it I will install a metal box with the power supply and a plastic box with the ESP8266 and logic shifter. Two 16-gauge multi-conductor cables run from boxes under the stairs to the LED strip. One cable is the power supply that goes to the bottom of the stairs then into the track up to the far end of the LED strip to inject 5v power. The other cable provides the 5v from transformer to ESP and level shift and then power and signal run to bottom step and bottom of LED strip.

I have zero electronic skills or programming ability, so I was thinking a motion detector would communicate with our home automation system which in turn would turn on the strip and it would run a series of commands to turn on segments in sequence.

Nice project! If you want to have the segments light up in order, and in the walking direction, you might want to keep an eye on this usermod, I hope it makes it into WLED soon:
