Greetings,
My name is Jeremy Trammell and I represent a group of developers and designers in Portland, Oregon. We have extensive experience with the Arduino platform and would be happy to assist you with your project. It's not entirely clear to me what you want, so I have placed an initial bid but we will need further clarification before we can proceed. I understand you have an Arduino connected to your X/Y motor controllers, how do you intend to communicate the control commands to the Arduino?
