Abstract
A motor controller used for driving a motor is provided. The motor controller includes a driving circuit, a control unit, an operational amplifier, a comparator, an inverter, a multiplexer, a first resistor, and a second resistor. The first and second resistors are mounted on a printed circuit board. By changing the resistance of the first resistor and the resistance of the second resistor, it is capable of changing the driving direction of the motor.
