This week we measured the power output of a motor.

To measure the power, we were told that we'd have to cut a trace and use the multimeter in series to get the current readings, which would allow us to calculate the power. We didn't want to sacrifice our boards by cutting a trace, so Anthony provided us with these nice USB plug-in devices for measuring voltage, power, and current.

We plugged it into the computer, which gave us the following readings for the entire board. Since the board consisted of just a motor, the readings are indicative of the output of a stepper motor.
