Make a Pro Micro with ATmega32U4 send key strokes using push buttons.
Uses Keyboard.press and Keyboard.release to support holding a button.
I needed a few buttons to use things like push to talk when using my turbo trainer.
Simplest solution: Put a keyboard next to the trainer.
Programmer solution: Use a Pro Micro with a ATmega32U4 chip to act as a simple keyboard and velcro push buttons to the handle bars.

- Connect the Pro Micro via USB
- Select Arduino Micro or Leonardo as Board
- Open the *.ino code file
