Introduction

This tutorial will guide you through using the IBT-2 BTS7960 motor driver with an Arduino. The IBT-2 is capable of driving a motor with a voltage range of 6-27V and a maximum current of 43A. This makes it suitable for various applications where you need to control motor direction and speed.

Step 1: Gather Required Components

Before starting, ensure you have the following components:

• IBT-2 BTS7960 motor driver board
• Arduino board (e.g., Arduino Uno)
• DC motor
• Power supply (6-27V) compatible with your motor
• Jumper wires
• Breadboard (optional)

Practical Tips

• Verify the voltage and current specifications of your motor.
• Use jumper wires of appropriate length to avoid clutter.

Step 2: Wiring the IBT-2 to Arduino

Connect the IBT-2 motor driver to the Arduino as follows:

1. Connect Power:

   • Connect the VCC pin of the IBT-2 to the positive terminal of the power supply.
   • Connect the GND pin of the IBT-2 to the ground of the power supply and the Arduino.

2. Connect Motor:

   • Connect the motor wires to the output terminals of the IBT-2.

3. Connect Control Pins:

   • Connect the PWM pin (e.g., PWM_A) to a PWM-capable pin on the Arduino (e.g., pin 9).
   • Connect the DIR pin (e.g., DIR_A) to a digital pin on the Arduino (e.g., pin 8).
   • Optionally, connect ENA (Enable A) to another digital pin for additional control.

Common Pitfalls

• Ensure all connections are secure to prevent intermittent issues.
• Double-check the power supply voltage before connecting to avoid damaging components.

Step 3: Arduino Code Setup

To control the motor using the IBT-2, you'll need to upload the following code to your Arduino:

#define PWM_PIN 9 // PWM control pin
#define DIR_PIN 8 // Direction control pin

void setup() {
    pinMode(PWM_PIN, OUTPUT);
    pinMode(DIR_PIN, OUTPUT);
}

void loop() {
    // Rotate motor clockwise
    digitalWrite(DIR_PIN, HIGH);
    for (int speed = 0; speed <= 255; speed++) {
        analogWrite(PWM_PIN, speed);
        delay(10);
    }
    delay(2000); // Run for 2 seconds

    // Rotate motor counterclockwise
    digitalWrite(DIR_PIN, LOW);
    for (int speed = 255; speed >= 0; speed--) {
        analogWrite(PWM_PIN, speed);
        delay(10);
    }
    delay(2000); // Run for 2 seconds
}

Explanation of Code

• The PWM_PIN controls the speed of the motor.
• The DIR_PIN sets the rotation direction.
• The loop gradually increases and decreases the motor speed to demonstrate control.

Step 4: Testing the Setup

1. Power on the circuit.
2. Upload the code to the Arduino.
3. Observe the motor's behavior:
   • It should rotate clockwise for 2 seconds, then counterclockwise for 2 seconds.

Practical Advice

• Ensure your power supply can handle the motor's current requirements.
• Use a multimeter to check voltage levels if the motor does not respond.

Conclusion

You have successfully set up and controlled a DC motor using the IBT-2 BTS7960 motor driver with an Arduino. You can further explore adjusting the speed and direction based on your project needs. As the next step, consider integrating additional features such as feedback control or remote operation.
