Introduction

Gravity 130 DC motor is a very interesting module, the module does not need additional motor driver board, you can use Arduino board to drive it easily. And the speed control could be realized with PWM signal. Very popular with DIY project.

Specification

    */

    int motorPin = 3;   //Motor drive pin D3
    int motorSpeed;     //Define motor speed

    void setup()
    {
      Serial.begin(9600);
    }

    void loop()
    {

      for(motorSpeed = 0 ; motorSpeed <= 255; motorSpeed =5)
      {
        analogWrite(motorPin, motorSpeed);   //PWM speed control
        delay(30);
      }
      for(motorSpeed = 255 ; motorSpeed >= 0; motorSpeed-=5)
      {
        analogWrite(motorPin, motorSpeed);   //PWM speed control
        delay(30);
      }
    }
