Im trying to compile a list of parts needed for this project...I think Im going to avoid using a PLC for now even though I am highly tempted to! When using thermocouples as your input and current in mVDC (converted AC current to DC using a current transducer)...unlike PLCs which have special thermocouple input cards, does ARDUINO or AVR need TC voltages programmed "by hand " or are they already programmed in them? Curious question since not familiar with programming that much.What hardware do I need?
