If you send a HIGH signal to the enable 1 pin, motor A is ready to be controlled and at the maximum speed.

The enable pins are like an ON and OFF switch for your motors.
L298N MOTOR DRIVER CONNECTION HOW TO
Now that you’re familiar with the L298N Motor Driver, let’s see how to use it to control your DC motors. You need to remove those jumper caps to control the speed of your motors. There are jumper caps on the enable pins by default.

The input pins are used to control the direction of your DC motors, and the enable pins are used to control the speed of each motor. If you supply more than 12V, you should remove the jumperĪt the bottom right you have four input pins and two enable terminals. Jumper removed: you need to provide 5V to the +5V terminal. Jumper: jumper in place – uses the motors power supply to power up the chip.Acts as a 5V output if jumper is in place +12V: The +12V terminal is where you should connect your power supply.For example, you can use a bench power supply to test this tutorial. In this tutorial will be using 4 AA 1.5V batteries that combined output approximately 6V, but you can use any other suitable power supply. It’s important to note that despite the +12V terminal name, with the setup we’ll use here (with the jumper in place) you can supply any voltage between 6V and 12V. Note: if you supply more than 12V, you need to remove the jumper and supply 5V to the +5V terminal. 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 +5V terminal. The +5V terminal is used to power up the L298N chip. The +12V terminal block is used to power up the motors. OUT1 and OUT2 at the left and OUT3 and OUT4 at the right.Īt the bottom you have a three terminal block with +12V, GND, and +5V. The motor driver has a two terminal block in each side for each motor. Let’s take a look at the L298N motor driver pinout and see how it works. The L298N motor driver is shown in the following figure: L298N Motor Driver pinout Additionally, it allows us to drive two DC motors simultaneously, which is perfect to build a robot. We’re going to use the L298N motor driver that can handle up to 3A at 35V. The method we’ll use here is suitable for most hobbyist motors, that require 6V or 12V to operate. There are many ways to control a DC motor. Power source: 4x 1.5 AA batteries or Bench power supply.ESP32 DOIT DEVKIT V1 Board – read ESP32 Development Boards Review and Comparison.To complete this tutorial you need the following parts: Installing the ESP32 Board in Arduino IDE (Mac and Linux instructions).Installing the ESP32 Board in Arduino IDE (Windows instructions).To better understand with this tutorial, you may want to take a look at the following posts: This tutorial is also compatible with similar motor driver modules. Note: there are many ways to control a DC motor. Then, we’ll show you an example on how to control the speed and direction of a DC motor using the ESP32 with Arduino IDE and the L298N motor driver. First, we’ll take a quick look on how the L298N motor driver works. This tutorial shows how to control the direction and speed of a DC motor using an ESP32 and the L298N Motor Driver.
