This code was developed as part of the CUES Hackathon 2016. The project is classification of body motions based on accelerometer data. This is implemented by 3 micro:bits attached to the arm at the shoulder, elbow and wrist transmitting their accelerometer data (using kf_transmitter) to the hub which sends all the data over the serial output to a computer. The further processing was prototyped in Matlab (code not in this repo).
The code uses the Lancaster University microbit-dal and bases code on their proximity heart sample. If you want to run this code, I suggest you look at their examples first to understand how to use the tools.
