Motion based PuckJS Media remote control

Thanks for all the good advice.

I think I need to lean some vector math!

my next steps are:

Use Vec3.js to calibrate my mag sensor and surroundings.

by adding a hold down the button for 4 seconds to calibrate feature:

To calibrate rotate the puck in all directions while sampling the mag data at a high rate, save the min and max value of each x,y,z axis.

Press button to exit calibrate

Take the average of the min/max for x,y,z and store these as JSON to a file in flash mem.

Sample at a lower rate and subtract the average x,y,z from each reading

use vector maths to calculate which way up the puck is and any clockwise or anticlockwise rotation steps.

Then I need to work out how to send HID command via BT

I will post an update as soon as I have made progress or if I have more problems. With some debug output this time.
