RotaryController

An Arduino sketch to turn a simple rotary encoder into a keyboard with very limited functionality.

Materials

1. An Arduino Micro. However, any other ATmega32U4 microcontroller should do.
2. A rotary encoder
3. 2 10K ohm resistors for the debounce circuit
4. 2 .1uF capacitors (I used ceramic 104 capacitors) for the debounce circuit
5. A switch

Setup

Most of the circuitry that does not involve the Arduino is the debounce circuit.
