This project enables people with physical disability to communicate through gesture using BBC microbits. One microbit is worn on the wrist (the transmitter) and a second is connected to a laptop or communications device (the receiver).
When a gesture is made, the motion is detected by the microbit on the wrist. This microbit uses its radio to signal the microbit connected to the laptop.
The microbit attached to the laptop then sends a trigger signal through the USB cable connected to the laptop. This signal is detected by a program running on the laptop which generates a simulated keystroke. This keystroke controls other software running on the laptop, such as communications software like Smartbox's Grid software.
The project website has full details of what this project does and a video showing the system in use.

transmit: software for the transmitter microbit
receive: software for the receiver microbit
base: software to run on the laptop that the receiver is connected to
docs: photographs and files to generate this README and the setup instruction

This contains links to videos showing how to set up the system.
Testing the system by using a hand shake to operate an LED.
micro:bit v1 was used for testing. The hex files in this repository also work with v2 of the micro:bit.
