StairLights is an Arduino-based LED stair way lighting project. It uses an Arduino, two IR transmitters, two IR recievers, and a strand of individually controllable LEDs to display light patterns on stairs when a person is walking up or down them.

Demo of it in action:



A circuit diagram is provided as a png and a Fritzing file. Missing from the diagram is the external power supply connected to the LED strand.

Once everything is wired up, load the sketch on the Arduino like any other sketch.
