L298N Motor Driver Module Features
The L298N module is used to drive DC motors with a maximum current of 2 amps. The L298N driver module is easy to use. It contains a good filter circuit and gives you access access to inputs and outputs via pin headers and terminals.
The L298N is a dual full-bridge motor driver that allows two DC motors to be connected simultaneously.
Note
This driver needs a logic voltage supply to drive the motors, which uses a 5-volt regulator to solve the logic voltage supply problem. This module features:
- Max operating voltage: 46 V DC
- Max output current: 2 A (Peak 3 A)
- Power: 25 W
- Input voltage level: 5 V
- Working temperature: -25 to 130 Celsius
Note
If the load on the motor is high, the driver temperature will rise rapidly. S Since the working temperature of the L298N is between -25 and 130 degrees Celsius, heatsink should be used to cool down the module.

Interfacing L298N Motor Driver Module with Arduino
Step 1: Circuit
The following circuit shows how you should connect Arduino to L298N module. Connect wires accordingly.
Step 2: Code

void setup() {
pinMode(8, OUTPUT); //IN2
pinMode(9, OUTPUT); //IN1
pinMode(10, OUTPUT); //Enable Pin
}
void loop() {
// Full speed forward
digitalWrite(8, HIGH);
digitalWrite(9, LOW);
digitalWrite(10, HIGH);
delay(3000);
// Full speed backward
digitalWrite(8, LOW);
digitalWrite(9, HIGH);
digitalWrite(10, HIGH);
delay(3000);
// 0 to 100% speed in forward mode
for (int i=0;i<256;i++)
{ digitalWrite(8, HIGH);
digitalWrite(9, LOW);
analogWrite(10, i);
delay(20);
}
delay(50);
// 0 to 100% speed in backward mode
for (int i=0;i<256;i++)
{ digitalWrite(8, LOW);
digitalWrite(9, HIGH);
analogWrite(10, i);
delay(20);
}
delay(50);
}
As you can see in the code, the motor first moves forward for 3 seconds and backward for 3 seconds. Then the motor stops and its speed increases from 0 to 100% in the forward direction with constant acceleration, and then the same movement is done in reverse.

Hello. I built the circuit as you said and set it up with the same code. But my DC motor did not work. After that, I connected the motor pins directly to the VMS and GND ports and the motor worked. Is there a problem with my board?
my Supply: 9V-1A
Hi oveas,
did you connect the GND pins of all components together?
