I trained the Lightning and Winding hand movements gestures (magic wand) by using Google Colab. Simply, just followed instructions from this workshop. Below scratch is my plan:

Since I can not find any push button, I used a jumper wire instead.

Even if I tried hard to perform the movements of Lightning. The result shows Winding movements is more easier to be classified than Lightning gestures. I guess, it is because they both have the same order of movements’ direction. I should use opposite direction order for this two gestures next time.

Classified result from Arduino Serial Monitor

Keru Wang has an interesting WebGL shader to demonstrate Lightning and Winding. I was planning to integrate it into my work by serial communication. So I can control the Lightning and Winding by hand gestures movements. However, I did not get luck for it yet.

Thank you.
