I am working on a hobby circuit. And got a quick question.
I am using regular mini DC Motor as DC Generator. If the motor is rotated one side it generates few volts. If the motor is rotated in opposite direction the output polarity is switched. Which is normal.
I would like to know how/what circuit to connect to output of Motor, such that if the motor was rotated in any direction, the polarity of the output after the circuit is same.
