A automatic light for under the bed.
It activates on motion, the sensors are placed so that they wont activate when you are in the bed. But when you step out of the bed or aproach the bed. They turn of after there has been no motion after a set time.
Because i dont need them to go on when its is light in my bedroom i added a ldr to measure the ambient light.
U used a cheap white led strip from ebay (search for led strip). I didnt used rgb because i just wanted to have light when i go to bed and when i get out of bed.
I mounted the ledstrip to the bed with the adhesive backing of the strip itself. I used alcohol to clean the area where the ledstrip would go so it would stick better.
My bed is made of wood, normally i would advise to mount a ledstrip on some aluminum for cooling. But because the leds are only on a couple of minutes or less its not necessary.
