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. Serial.The motor driver has a two terminal block in each side for each motor. Move DC motor forward with increasing speed Move DC motor backwards at maximum speed Move the DC motor forward at maximum speed

attach the channel to the GPIO to be controlled Make sure you have the right board and COM port selected. Arduino Sketch to upload in ESP32Ĭopy the following code to the Arduino IDE and upload it to your ESP32.

Refer below given schematic for your ready reference.Īs shown in below schematic GPIO14 connected to Enable pin and GPIO27 & GPIO26 Input 1 and Input 2 of L298N-Bridge Motor driver. Please refer my previous tutorial for pinouts and there possible configuration. We will connect the Relay module at GPIOs 4. Please refer below pinout for ESP32 with 38 Pin to build the schematic for this project. ESP32 (read Best ESP32 development boards).To build this project we need the following parts: Now, we know how to control a DC motor with the L298N motor driver, let us build the simple example to control the speed and direction of one DC motor.

If you want the motor A to rotate in one direction, apply a HIGH pulse to IN1 and a LOW pulse to IN2. Input 1 and input 2 control motor A, and input 3 and 4 control motor B. The input pins control the direction the motors rotation. However, note that for small duty cycles, the motors might not spin, and make a continuous buzz sound. The motor speed is proportional to the duty cycle. If you send a PWM signal, you can control the speed of the motor.If you send a LOW signal to the enable 1 pin, motor A turns off.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. Now, that you’re familiar with the L298N Motor Driver, let’s see how to use it to control your DC motors. 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.
