By understanding this concept, you can implement several Motor related Projects with Raspberry Pi like:.

The aim of the Raspberry Pi L298N Motor Driver Module Interface is just to understand the concept behind controlling a simple DC Motor with Raspberry Pi.

I think the commands are self-explanatory.

e – exit (to stop the motor and exit Python).

h – high (to increase the speed to 75% level).

m – medium (to run the motor at medium speed 50%).

l – low (to decrease the speed to 25%) – default speed.

b – backward (to reverse the direction of rotation).

f – forward (to run the motor in forward direction) – default direction.

This is followed by a list of commands you must use to control the motor. You will get a message regarding the default speed and direction of the Motor. After creating the Python Script with the above code, run the script.

If you take a look at the code carefully, you can easily understand the working of the project. We will see the explanation of the code in the Working Section. The Python Script for Interfacing L298N Motor Driver Module with Raspberry Pi is given below. The rest of the job is done by the Python Script. In order to do that, connect the ENA pin of L298N to Physical Pin 22 (GPIO25) of Raspberry Pi.Ĭoming to the Inputs of the Motor, connect the IN1 and IN2 of L298N Module to Physical Pins 16 and 18 (GPIO23 and GPIO24). Now, since we are controlling a single DC Motor, we need to use a single channel of the L298N. Then, make the GND terminals of Raspberry Pi and L298N Motor Driver Module common (connect them together). First connect 12V Power Supply to L298N Motor Driver Module. The design of the Raspberry Pi L298N Motor Driver Interface Circuit is very simple.

12V Power Supply for Motor and Motor Driver.

The circuit diagram is made with the help of Fritzing App. The following image shows the circuit diagram of the Raspberry Pi L298N Motor Driver Module Interface. If it is more than +12V, then disconnect the jumper to disable the regulator.Ĭircuit Diagram of Raspberry Pi L298N Interface

This must be used only if the supply voltage is less than or equal to +12V.

If it is connected, it will enable the on-board 5V regulator, which supplies +5V logic supply for L298N IC.

There is jumper near the power supply terminals of the L298N Motor Driver Module.

To name a few, it contains screw terminals for connecting motors and power supply, male headers for connecting different pins like enable, IN1, IN2 etc. The above image shows the L298N Motor Driver Module with names of all the components on it. This IC, along with few other extra components make up the L298N Motor Driver Module.

The pin diagram of the L298N Motor Driver IC is shown in the image below. The L298N Motor Driver Module is based on the powerful L298N Motor Driver IC. It became so popular that the module is now available at a very low cost.

In recent times, L298N Motor Driver Module has become the favorite choice of hobbyists and makers when it comes to DC Motor Control. So, first, let me take you through a simple introduction to L298N Motor Driver Module. How different will it be for controlling a DC Motor using Raspberry Pi with L293D and L298N? Well, there won’t be much of a difference as essentially both these modules serve the same purpose.īut it is always nice to learn about something new and implement it into a project. If you remember, I have already made a project on CONTROLLING A DC MOTOR WITH RASPBERRY PI using L293D Motor Driver. When I say control a DC Motor, I mean you can start a motor, stop it, make it rotate in forward direction, backward directions, increase the speed of rotation and also decrease the speed.įor this, I’ll be using the L298N Motor Driver Module.
