I was wondering if there was already an external to control a printer or a robot with PD.  If not, does anyone know how I would go about writing one? I understand that if you were to write a binary, you’d probably have to understand C (or C+ or C++… whatever it’s called). Obviously, I don’t understand any of it. If anyone can help me, let me know.

Thanks,

Robert

P.s. (if there is an external for the robot stuff, is there a specific kit that would be best for PD?)
