I am the president of the e-NABLE program at Siena College and I am trying to build this arm for a recipient in need. I am having trouble with the electronics. I have had experience in circuits but I seem to be running into a lot of issues. Firstly, I was wondering if you used an arduino micro because it seems that the code is too big for the micro. In addition i was wondeirng if you have a schematic or a picture of your circuit that you can send me. You can email me back at email@example.com if preferred. I would really really appreciate it if you could help me out with this. Besides me, it will greatly help the girl I am working with who is really looking forward to this arm.
