HS-F10L-B Dual Channel MOC Motor Driver Module

1. Introduction

This is a motor driver board developed for the Lego technology building block motor and steering motor, compatible with most Lego motors, and also supports Lego battery power supply.You can control the rotation and stop of the Lego motor through the high and low levels of the two IO ports of the microcontroller, and you can also control the Lego steering motor. By switching the high and low levels of the two IO ports, you can achieve forward and reverse rotation.You can also use PWM pulse width to adjust the motor speed, the motor cannot rotate when the voltage is below a certain value.

10, Test results

Arduino UNO Test Conclusion:

After the device is connected and the program is uploaded to the Arduino UNO development board, it will be found that the motor will rotate for 2 seconds and stop for 2 seconds and then continue to cycle.Now you must have mastered the basic theory and programming of DC motors.You can not only make it go forward and backward, but also adjust its speed.In addition, you can use the knowledge you have learned to make more wonderful applications.
