Firmware for woot-light project.

This project is a simple automation of a pair of Woot-Off lights

Requires a Blue Pill STM32 board, a couple of 2n2222 BJTs, a couple of 1k5 resistors, wire, and a case.

The Blue Pill is powered by the USB and this provides enough power for the lights as well.

Use is simple, connect to the USB serial port.

• ? displays build info and is useful to verify the serial connection.
• o mask time is used to turn on one or both lights for a specified time.
  mask is a bitmask of the lights. 1 is for light #1, 2 for light #2, 3 for both.
  time is the time to activate the lights in milliseconds with a maximum of 1 minute.
