|
|
|
|
|
- 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.
