I'm trying to control a RC Car composed by one motor and one servo. The problem is that the RC Car is quite old and I don't have much information bout the components. The RC car, was poweres by a 7V-1200mAH Battery, but this battery doesn't work anymore. I isolate the motod and the servo from the central chip in order to make my own circuit with arduino.
I try to plug a 9V Cell. I got an ohmeter and the motor have 55ohms of resistance.
How can I know the maH that the Cell have? How can I make this motor run?
PS: The motor only have 2 wires. One red and another blue. I tink that its a positive-ground only powered motor.
Thanks in advance!
