A L298N Dual H-Bridge motor driver module.

As a first step, you will need the following parts for interfacing a L298N dual H-bridge motor driver module with the Arduino Uno: Now that we know the bare minimum of the L298N dual H-bridge module, let us look at how to interface it with the Arduino Uno. The GND port should be used to tie the circuit with a common ground. Whereas the 5V port can be used for connecting to Arduino's 5V pin. The 12V port is to accept external power supply ranging from 5 - 35 volts - the module has an in-built 5 volt power supply unit to manage the power at the required level. You will have to use either the 12V or the 5V power port for powering the module - don't use both together. For this take a look at the next diagram.įigure 3 - L298N Dual H-bridge power pins with Arduino Uno Once the DC motor has been connected, the next steps is to make the power port connections. These terminals have to be connected with the motor connection ports as shown below.įigure 2 - L298N Dual H-bridge with DC Motor

However, this post will be using the L298N module that has a dual H-bridge circuit mounted on it.įigure 1 - An L298N dual H-bridge module with Arduino UnoĪs shown above, there are two motor ports on either side of the L298N dual H-bridge module. The H-bridge circuit can also be procured separately as a single packaged board if necessary. An H-bridge is a special circuit that can be used to drive DC motors in forward as well as reverse polarities with PWM ( Pulse Width Modulation) speed control.

The L298N is a circuit board with two H-bridge circuits mounted on it. In this post we will look at how to use the L298N dual H-bridge motor driver module with the Arduino Uno. By Kallol Bosu Roy Choudhuri Author of Learn Arduino Prototyping in 10 Days
