How to use motor driver L298N – Arduino tutorial

Hellloooo people, today we’ll be seeing what is a motor driver module, how to use it and where to use it – its connections and coding. So without wasting time, let’s directly jump to our motor driver L298N Arduino tutorial.

What is motor driver ?

The thing is whatever you do, the Arduino supplies maximum of 5V 1A as output; which is enough to power LEDs or smaller applications but not a motor, a LED strip or our bot! So for applications demanding more current or voltage we need a higher power source as well as a means of control. This is where motor driver comes into play, it lets more power flow through itself by taking commands from the Arduino, simple?

So first things first,

Requirements –

• Motor driver module L298N
• 2 9V batteries
• Arduino Uno/Mega
• A 50/100/200 rpm motor
• Jumpers/Wires
• A slice of Pizza to celebrate 😉

Connections of Motor driver L298N – Arduino tutorial

12V – Battery +ve
GND – Arduino GND, Battery -ve
2 Signal pins – Pin 7 & 8 of Arduino
2 wires from application terminals – motor wires

Code –

void setup() {
  
  pinMode(7, OUTPUT);
  pinMode(8, OUTPUT);
  }


void loop() {
  digitalWrite(7, HIGH);   //clockwise rotation
  digitalWrite(8, LOW);
  delay(5000);
  digitalWrite(8, HIGH);   //anticlockwise rotation
  digitalWrite(7, LOW);
  delay(5000);

}

That’s it! Power up your Arduino with your cable or battery and you are good to go. Here is a video tutorial which will make things super easy for you!

Also here is a video tutorial on Obstacle avoiding robot using an ultrasonic sensor and this same motor driver module..! Go try it, what are you waiting for? It’s a mere 10 min job!
