# Macro Keyboard with Rotary Encoder This project is designed for Arduino Micro boards and functions as a **macro keyboard with rotary encoder**. Eight mechanical cherry MX keys can be assigned various functions (writing text, combination and sequences of key codes, multimedia and mouse functions). Rotary encoder supports turning, click and double click. ## Features * Up to 4 keys codes sent at once * Sequence of maximum 16 length of separate key commands * Modifier key to change the default behavior of rotary encoder * STL files for case * All keys are directly connected to GPIOs, so no diodes are required * Can emulate keyboard, multimedia key, mouse and system commands This project is inspired by [Control volume knob by Prusa](https://blog.prusaprinters.org/3d-print-an-oversized-media-control-volume-knob-arduino-basics/) and some code is taken from it. ## Prerequisites ### Hardware * 8x Cherry MX keys - I have used red ones * 1x 25cm micro USB cable - you can use any micro USB cable * 1x Arduino Pro Micro 5V - as the board is powered from the USB, ie. with 5V, you can solder the J1 solder joint to bypass the LDO * 1x rotary encoder - make sure it has thread to secure it on the case * Optional - silicone wires - in comparison to my old wires, these are angel's stuff. I have used AWG26, but I suggest to use AWG 28, there are no big currents. ### Software Project was tested with following version: * Arduino IDE 1.8.12 * Arduino AVR boards 1.8.2 Libraries: * [ClickEncoder](https://github.com/0xPIT/encoder) * [TimerOne 1.1](https://github.com/PaulStoffregen/TimerOne) * [HID-Project 2.6.1](https://github.com/NicoHood/HID) ## Setup Detailed setup steps are described on my [Github](https://github.com/mensikv/VMs-macro-keyboard). ## Additional STLs Aside from the provided files you need: * 8x KeyV2: Parametric Mechanical Keycap Library - I have used oem_row-5_length-1.stl * 1x volume knob - I have used knob_smooth_playpause.3mf
