Re: MicroControllers at competitions

Sorry. I just got home from school. I don't have one yet, but I was thinking of a very small shunt. The main point of this would be to find shorts. Also, I don't think it is illegal. You can have things between motors, as long as they don't change the power. In this case, the power difference would be so minuscule, that it would just be ignored. I wanted to use Ohm's law to get a precise measurement of a high amperage. For that, I wanted to use the MCP3204 ADC to measure the voltage drop, and plug that into the formula, to get the exact amp draw. Last year, that would have been useful because we had no idea how to check what was shorted, so we had to use trial and error. It would have told that our motor controller was shorted (though we could tell because of hot the wires were getting!)
