Commumicating Arduino to Computer

One NRF unit connected directly to Arduino mounted on wrist device, the other NRF unit connected to an Arduino connected via USB adapter directly to computer.

Important Notes

• In order to utilise the "Keyboard.h" library, an Arduino Micro or Leonardo must be used.
• A special NRF Repository was acquired from this link.
• On the NRF24L01 module, a capacitor was placed across the connection of the VCC and GND to provide a consistent current.

Old Considerations (Using Bluetooth Device):
