Re: Voltage sensor
If you check the forum from back in believe it was May or June there was a thread on Victor voltage output, PWM, h-bridges, FETS and more. You may want to review that entire thread and some the links that were posted. After you read that you'll find that current is probably a better measure of the power going to a motor. To measure current, First provided an Allegro current sensor in 2004. Your team may already have the hardware to measure current. You can look in the First 2004 archive and find the data sheet. The Allegro sensor is a hall effect device and outputs a voltage that can be read by one of the FRC analog to digital ports. There are other ways to measure current but the Allegro sensor is a good choice for the high amps our motors draw.
