Tell us about yourself!
This is a great project and I love the results but I was hoping you would have some link to a simpler version we could do at home.
Welcome to Arduino
I like this but I have a problem. Do you have a full schematic of the layout of the circuits? All I see here is lables for the pc board. I would like to prototype this but can't from the info provided here. Thanks.
If you flip your Crescent wrench over it will fit any metric nut or bolt.
