DIY Arduino based LED Stair Lights Automation

An automatic stair lighting system is one which lights each step LED when a user starts to climb or descend.  Erica Kane has developed a similar Open Source DIY Automated LED Stair Lighting system using an Arduino Pro Mini, a M5451 LED Display Driver to power the LEDs and a PING ultrasound distance sensors to detect when someone enters the stairwell.

The Eagle schematic file is here and the Arduino Processing environment can be found here. You can edit this to add more lights, or to use a different lighting sequence. This code uses the Lightuino source code to drive the M5451.
