attention engineers!
I need some advice from someone who knows about electrical engineering (or hardware or whatever).
I have this robot. It has three input wires -- one is ground, the other two are voltages between 0.5V and 4V. I want to be able to write code on a laptop to determine what voltages to send to the wires, and send it. Obviously I need a piece of hardware that will hook up to my USB port or that I can put in the PC slot which will let me connect wires on the other end and send outputs.
Will this piece of hardware do what I want? If not, what will?
The sooner I figure this out the better, so please give me any advice/info you have! I know there are at least a couple engineers reading my LJ . . .
