|
||||
Program tested on Arduino Pro Mini (flashed with avrdude using the Makefile). |
||||
|
||||
**Connections** are `#define`d in `main.c`, board size and snake speed can also be adjusted. No external parts except the display and buttons required. |
||||
|
||||
Best works with a gamepad, but any buttons will work. |
