So I have bought: RobotShop | Robot Store | Robots | Robot Parts | Robot Kits | Robot Toys

A Motor controller to control my DC Motor.

After an hour and half of trial and error, I still could not power my DC motor.

I have tried sending digital signals of HIGH and LOW to different pins on the motor controller, but still no luck.

Just wondering if anyone happen to know how to operate this board. I just need a basic ON / OFF and DIRECTION for a DC motor. NO need for speeds. Thank you.

I have output a PWM signal into pin 5 and a HIGH on pin 3 on the motor controller

How they connected:

Arduino - Motor Controller
Pin 3 --- Pin 5
Pin 2 --- Pin 3

but the DC motor have yet to be driven. Even the LED lights that signals backward & forward direction of the DC motor were not lit up at all.

I just want to be able to move the DC motor forwards and backwards.

My code is:
void setup() {
Serial.begin(9600);
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
}

void loop() {
analogWrite(3, 255);
digitalWrite(2, HIGH);
}

Have you connected a motor power supply?
Have you connected the ground to the arduino ground.
You are using pin 3 as a PWM pin. This pin is not capable of PWM, use a pin that is, like pin 5 or pin 6.
