Are there any sensors i can attach to my hand to track its left and right movement?
Glove project. Say moved my hands 96cm apart, the arduino knows they are 96cm apart
Thank you
That would be cool sensors.
Maybe you should measure the angles of the shoulders, elbow and wrist and do some 3D goniometry?
