 A wide range of Arduino boards supports HID (Human Interface Device). Often these are to emulate simple keypress' but to do more complex things like send one or modifier keys with a key - or to emulate holding a key down for a set period of time is either impossible or difficult to implement. Adafruit has developed the firmware on their Bluefruit nrf\* range of boards to emulate HID keyboards well using their AT Commands.

 If you are using a receiver dongle - follow the same guidance below but you will also need to copy over the firmware file for the dongle. Same procedure - different file name
