Controlling DC Motor using L298N and Arduino UNO

 

Remote controlled and autonomous cars fascinate everyone. And being able to understand their working, and most importantly, being able to make them is a wonderful skill and experience. But, before we jump onto that, it's important to learn about two key components of such cars, MOTORS, and MOTOR DRIVERS.

Explaining in the simplest possible way, MOTORS are output devices used to rotate wheels, by using electrical power.




And MOTOR DRIVERS are modules used to control the direction of rotation of motors, clockwise or anti-clockwise, and speed of rotation of wheels. 



We will now make a simple project, in which we will control our motor's direction using a motor driver, L298N. 

Hardware Components Required

1- L298N Motor Driver
2- Arduino
3- Motor
4- Wheel
5- Jumper Cables
6- Battery (9V)

Checking Motor and Motor Driver

Before starting any project, make sure your hardware is working correctly. The following method may be used to check for motor and motor driver's basic working.

Motor

Patch the circuit as shown in the image below. If the motor turns on, and the attached wheel rotates, then your motor is working correctly. 


Motor Driver

Patch the circuit as shown in the following image. If the light in the module turns on, then the basic working of L298N is fine. In some cases, you may need to do a deeper diagnostic test, depending on the situation. In that case, you may contact us for proper testing methods.

After learning the basics, we are now ready to make our 1st car. Stay tuned for our next video, and if you have any queries feel free to ask us in the comment section. :)

How To Make Line Follower Car with Speed Control | 6 IR Sensor Arduino Line Following Car

Image
It's easy to make a robot that follows a line or smooth curves, but it becomes challenging to design the line follower robot when its track is complex. But we got you covered. Using 6 sensors and speed control of our car, we'll design our fast and advanced line following robot.  Before starting on this advanced project make sure you understand How Does An IR Sensor Works  and have tried making 2 Sensor Line Follower or 3 Sensor Line Follower . Hardware Setup Components Required Arduino UNO Motor Driver L298N 6 x IR Sensors (1 x TCRT5000 & 1 x HX-01) Car Chassis (Base & Motors & Wheel & Caster Wheel) 12V Battery Pack Jumper Cables Car Chassis Assembly Circuit Diagram Note: For speed control remove the tiny black jumper covering ENA and ENB pins on L298N. Make sure they are covered when not using the speed control, else project may not work.
