The RGB Rainbow Sun is your own personal rainbow factory! Add color to your life with this DIY gadget. It is an interactive light that senses touch, sound, and ambient light. Pre-programmed to work out of the box, the software is open-source and built on top of arduino . You can program light transitions depending on your mood, the time of day, or the sound in the environment. You can connect more RGB LEDs to make a wall of light! Powered by AAA batteries OR USB (whichever you got!)
