Spatial RGB

What

• Arduino
• 3 sonars
• 3 colors in the spectrum
• RGB LED strip
• Magic!

Building

To run this project, you need Arduino Pro Mini, or Nano (those $2 eBay clones will work perfectly). You can also try to use a genuine Arduino, even larger (UNO), though I haven't tried that.

To flash the firmware, run make flash. Adjust the Makefile as needed. Naturally, you'll need avr-gcc and avrdude installed (and Linux or OSX).

Make sure the correct Serial device is defined in the Makefile (/dev/ttyUSB0 or other - it tends to be something really strange on OSX).

Hardware

• RGB LED strip with WS2812 or WS2812B. It's set up for a 30-led strip, adjust as needed.

• Sonars: HC-SR04 (you can get them on eBay)

Wiring is configured in the C file at the top - adjust pin numbers however you like.
