I am new to Arduinos and was hoping to get some insight into a project I'm putting together.
Basic procedure - Monitor a particles location with a camera, when the particle moves (detected by a LabVIEW VI) begin a feedback cycle with an Arduino that is hooked up to a high voltage DC power supply and function generator (acting as an AC power supply). The feedback would be changing DC V and AC frequency, checking the particles location, changing, checking, etc. until the particle is back it's original location.
My main concern at this moment is the supplies we'll need to do this. The remote connections are RS232 on the function generator (for which I see there are shields available) and J107 on the DC power supply (where the voltage put out by the supply is set by a voltage input ranging from 0 to 5 V DC on one of the pins).
- Are there any RS232 shields that come highly recommended? I've seen a lot about building your own serial connection but would prefer an off the shelf item the folks have had success with in the past.
- Do I need two Arduinos, one for communicating with the function generator (RS232) and one for communicating with the DC power supply (J107), or can this be done with one Arduino?
- Along those lines, can an Ardiuno supply a variable voltage output? Or do I need to control something that will give me a variable voltage output to then control the DC power supply? Or a yet unthought of combination?
Thank you for your help. I'm happy to elaborate or answer any questions as needed.
