To control the motors of the robot need a device that has converted to control signals in the low-power currents sufficient to control the motors. Such a device is a motor driver.
HG7881 strong> - is a dual motor driver, power possible from the source of 2.5 - 12V output driver Description:
Output Description
In order to make the engines work necessary to us on the way conclusions (B-IA, B-IB, A-IA, A-IB) must be submitted logic signals (HIGH, LOW).
PWM pulse width modulation signal is used to control motor speed, a digital output is used to change the direction.
