I have very little hands on experience with the Arduino (never got around to buying one), but I've read lots about it, watched Maker podcasts, etc.
I'm curious, from a components (probably the wrong word) standpoint, what would I need to create a wristband that could detect if a finger is 'down' (finger to the palm) and which one, and that an LED would show on the wristband which finger was down.
Thanks, I hope this made sense. My coherency levels go down after two nights without sleep.
Hi, thanks for the reply! I'll look through those links.
For my purpose, it doesn't matter about the position, just which finger is down or not. For me, I can physically see different muscles on the lower part of my wrist when I put a finger down. Would EMG be necessary, or can the patterns be recording by a piezoelectric sensor?
Can you put something on the palm and on each fingertip? Is it sufficient to just test if the finger and palm are in contact?
I've never worked with one (but have one that I've yet to play with), but maybe a hall effect sensor could be used to see if the finger is closer or farther away from a magnet on the wrist. I've never used one so I'm not sure how well they would work in this scenario. Richard probably knows.
