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
Those who are having foot lights in their stairway, then acme663ryo has an interesting stuff for you. According to acme663ryo, your foot lights are having epoxy pools of glass in the knot holes. These can be triggered by any light motion sensor, which in turn drives a solid state relay. The relay during its active cycle switches your DC power supply ON and through which you can connect your LED lights. In
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,
Instructables member Quanchante shared an interesting project of building a relatively cheap and pretty darn easy-to-assemble step lights made out of LEDs. If you are interested then get ready with the following Materials:  Glue gun and glue sticks Soldering gun and solder Felt or Thick fabric that matched the carpet on my existing steps 5mm UltraBright LEDs, color: Pure White with clear lens (3 per step light) 9v Battery (1 per step light)
Kakuniezti has uploaded an amazing video tutorial on YouTube with the help of that you can build your own auto LED lighting stairs. You can also watch this video below:
Technabob shares a new light designed to look like the glass is filled with milk, yes milk!!. This impressive lighting gadget lights up when placed upright and turns off when tilted or placed upside down. It also capable of creating a graceful and warm-heart conditions. You can find it at eBay for $9.99 or you can head to Wholesale Forum to get it slashed by half to $4.50. Watch this video to
 Fiberopticlight presents an amazing step lights created using Poly Optics Super Side Light fibre lit with LEDs at each end. Each strip of stairs consists of a single LED at each end of a 7mm Super Side Light fibre strip encased in a 10mm square polycarbonate extrusion. Entire system of strip lights is typically operated by just a single 9V power supply and the current consumption of each strip light is about
