This LED Stair Lighting Controller will make your home look amazing. The idea is to control two sensory infrared “beams”–a lower beam for the bottom step and another at the top of the stairs. Whenever the beam detects something interrupts (like feet) then the stairs light up, and after a 15 second delay, the lights will then automatically turn off. This install was done with custom blue 5mm LEDs, the

Instructables member ElJefeUno brought an awesome electronics project of building an Infra-red (IR) light trip sensor to light up your stairway. The sensor uses a directional IR LED beamed at a sensor that shoots past where you’ll walk. When you interrupt the light from the LED, the LEDs turn on for a period of time that you can adjust. Advantages of using IR LEDs includes: safe operation, low power consumption,
