  • Page 34: L298N Motor Driver

    L298N Motor Driver There are many ways to control a DC motor. The method we’ll use here is suitable for most hobbyist motors, that require 6V or 12V to operate. We’re going to use the L298N motor driver that can handle up to 3A at 35V. Additionally, it allows us to drive two DC motors simultaneously, which is perfect to build a robot.
  • Page 35 L298N Motor Driver pinout Let’s take a look at the L298N motor driver pinout and see how it works. The motor driver has a two terminal block in each side for each motor. OUT1 and OUT2 at the left and OUT3 and OUT4 at the right.
  • Page 36 At the bottom you have a three terminal block with +12V, GND, and +5V. The +12V terminal block is used to power up the motors. The terminal is used to power up the L298N chip. However, if the jumper is in place, the chip is powered using the motor’s power supply and you don’t need to supply 5V through the terminal.

    Control DC motors with the L298N Now that you’re familiar with the L298N Motor Driver, let’s see how to use it to control your DC motors. Enable pins The enable pins are like an ON and OFF switch for your motors. For example: If you send a HIGH signal to the enable 1 pin, motor A is ready to be controlled and at the maximum speed;...
  • Page 38 If you apply power the other way around: HIGH to input 1 and LOW to input 2, the motor will rotate backwards. Motor B  can be controlled using the same method but applying HIGH or LOW to input 3 and input 4. Controlling 2 DC Motors –...
