Tutorial: How to use L298N Dual Full Bridge Driver IC

The L298N IC is a motor control module for DC and stepper motors. It is ideal for projects requiring the control of two independent motors.

What you need

• Arduino Uno
• DC or stepper motors
• Jumper wires

Steps

1. Connect the VCC and GND pins of the L298N to the project power supply.
2. Connect the IN1, IN2, IN3, IN4 pins to four digital pins on the Arduino for motor control.
3. Power the motors through the 1A, 1B, 2A and 2B pins of the L298N.
4. Write the Arduino sketch that controls the motor operation.
5. Check the datasheet for proper motor DC or stepper power supply.
6. Test the functionality with a simple example program like changing direction and speed.
7. If necessary, add a resistor between the IN pins of the L298N and the Arduino to limit the current output from the Arduino.

Example code

void setup() {
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
}

void loop() {
digitalWrite(2, HIGH);
delay(1000);
digitalWrite(2, LOW);
delay(1000);
}

Mini project

Create a basic control system for two DC motors that alternate direction and speed every minute.

Common mistakes

• Do not check the proper power supply for the motors.
• Omit the resistors between the IN pins of the L298N and the Arduino.
• Use an insufficient number of connections to connect the module to the Arduino.
• Do not test the system’s functionality before its final implementation.

Recommended accessories

• Resistors
• DC or stepper motors
• Batteries or compressed air
