Hi all, this is my first arduino project, and I thought I'd post in case anyone's interested.
I got a five-axis robot arm for christmas (John Lewis own brand, actually the same as OWI-535) but it doesn't have a computer interface. I like making things, so I thought I'd see what I could do myself. After a bit of googling, I bought an arduino duemilanove because it's cheap, mac compatible, and can be configured with six pwm outputs, six digital outputs and six analog inputs.
What I couldn't find was a six-channel motor driver shield, so I thought I'd try to build my own. I've just finished testing it, and it works! More details to follow.
Barney.
