hi,
It's my first time working with Arduino, it's also my first time posting here, i have been working on a bionic hand that takes the signals from an EMG sensor placed on my arm to actuate 6 servo motors. each servo is connected to a dependent finger, the 6th servo actuates the wrist. I managed to contract and relax all the fingers at once using a code that i came a cross on Github, my question is: Is it possible to actuate each finger separately using only one EMG and 3 electrodes?
if that's possible, could you guide me where i could find a "ready to go" code that does not need lots of modifications?
With single EMG channel like you have, you can't extract data about multiple fingers. Roughly speaking, you need one EMG channel per finger - with smart enough processing, you can extract 5 fingers states out of 4 EMG channels, but not more. You can check what I was able to get out of 3 channels: Robotic Hand Control Using EMG - Hackster.io - that's near the limit, I've experimented more, with new sensor versions, with much more complex processing - and the best I could get out of 3 channels it's 4 finger sates.
