[CAVEAT: Very basic question from someone who is not yet even at the "newbie" stage. Please forgive if the question is too basic and/or poorly formed. --thank you!]
I work for a small start-up firm with very little by way of capital resources (translation: cheap and stingy!). We are about to start production of our new product and the idea came to me to try and automate the test procedure by building a computer-driven test fixture. I'm looking for some basic advice on 1) if the project is even feasible and 2) if so which platform would be better suited for it: Arduino? Raspberry Pi? Something else I've not considered?
The test procedure basically involves hooking the unit to a power supply. Driving the unit at standard power to check functionality. Lowering the voltage to check "low voltage" functionality. Raising the voltage to check for "over voltage" conditions. Then reversing polarity to check reverse polarity protection.
Since the fixture is computer-driven, seems using a raspberry pi is the choice (running something akin to LabView maybe? Is there a open-source freeware version of that available?) But then I have also read that for interfacing with and driving hardware the Arduino board is the better choice.
Any and all advice appreciated!
