Interactive LED-lamp with gesture sensor using Arduino.
A led strand (paste link) and plastic cups were used to assemble the lamp. (see video : Light ball using arduino and Adafruit RGB LEDs )
The LEDs were ordered in two lamps according to the following scheme:
The end result looks like this:
12mm Diffused Thin Digital RGB LED Pixels (Strand of 25) - WS2801 ---> Actually the strand I used has 50 LEDs, but it has also WS2801 chip (Amazon link)
