Features

• Effective for controlling high-power DC motors.

What it is for

The BTS7971 is ideal for projects requiring the management of high currents, such as building robots or automated mechanical systems. It is compatible with Arduino and similar microcontrollers.

Tutorial: How to use BTS7971

The BTS7971 is a motor driver that allows controlling DC motors with Arduino. Useful for projects requiring the management of high currents.

What you need

• BTS7971
• Arduino
• Pull-up resistor
• Power cable
• DC motors

Steps

1. 1. Download the BTS7971 driver for Arduino from the Arduino library.
2. 2. Connect the VCC of the BTS7971 to the 5V of Arduino.
3. 3. Connect the GND of the BTS7971 to the GND of Arduino.
4. 4. Connect the IN1 pin of the BTS7971 to a digital pin on the Arduino (e.g., 2).
5. 5. Connect a pull-up resistor (10kΩ) between the IN1 pin and VCC.
6. 6. Connect a DC motor to the OUT1 and OUT2 pins of the BTS7971.
7. 7. Load the example BTS7971 code onto your Arduino.
8. 8. Check that the motor moves forward and backward.

Example code

```
#include <BTS7971.h>

BTS7971 motor(D2);

void setup() {
  motor.begin();
}

void loop() {
  motor.forward();
  delay(1000);
  motor.backward();
  delay(1000);
}
```

Mini project

Build a simple robot that moves forward and backward using a DC motor and the BTS7971.

Common mistakes

• Fail to connect the pull-up resistor correctly.
• Use a DC motor incompatible with the maximum current.
• Forget to load the example code.
• Connect VCC to 3.3V instead of 5V.

Recommended accessories

• DC Motors
• Pull-up Resistor (10kΩ)
• Power Cable
• Electrical Protection
