/**
 * BLE WASD Keyboard V3
 *
 * Daniel Nugent
 * Dorian Rudolf
 * Michael Cox
 *
 * This program uses an adafruit BLE + Micro microcontroller to decode PS2, remap the scan codes to HID, and send over bluetooth GAT
 * Additional parts include the the tricket lipo backpack, WASD code keyboard, microusb male, and 3.7v batteries
 *
 * Ctrl + Shift + esc will reconfigure the keyboard
 *    -Use on first use or if the bluetooth module freezes or changes name
 *
 * Make sure you keyboard can run on 3.3v or make sure you can provide  it with 5v
 *
