The firmware for SourceBots' Arduino Uno board.
It communicates using commands sent over the USB serial pins.
Commands consist of a single character, followed by up to two arguments. The command is not separated from the first argument, but the first and second argument are separated by a space.
Request IDs can be specified by prefacing your command with @int, for example @8335. This is then returned with the command response and can be used to prevent race conditions.
