What your goal is (i.e. what problem you are trying to solve).

I wanted to create a wirless wand that I could use to train wekinator to recognize simple harry potter spells.

How you approached the problem, including

Sensors used

Accelerometer on microbit (XYZ)

Feature extractor approach (if you tried several ways to do this, document your work)

I began using only one microbit because I had trouble with the wireless microbit solution last project, but was eventually able to get the wirless working. It ended up being a problem with transferring the hex files. When I was downloading just the hex files from github it was corrupting them somehow. When I downloaded the whole folder as a zip it worked.

ML model structure - what you did and why, including results from experiments you tried along the way

I used DTW with 4 different classes. Based on the demos from Thursday I knew it would be a good idea to create a no spell sort of class to reduce noise and that worked quite well for me. My other 3 classes were the spells Incendio, Wingardium Leviosa, and Mimblewimble respectively. All 3 spells are fairly accurate, and that is demonstrated in the demo video.

Ideas about how other might improve upon your work

I would like to include a fun output with some animation that shows the spell you are doing or maybe use the microbit LEDS to create that effect.
