If it is greater than 12V, you should remove the jumper to avoid the onboard 5V regulator from getting damaged. Input 1 and Input 2 pins are used to control the direction of Motor 1 is connected to pin 13, pin 12 of the Arduino respectively. Here is a simple explanation of H-Bridge motor driving. But first, we must answer some basic questions like what is a motor driver, why is it used in a circuit, and what is an H-bridge configuration, etc. When you’re done you should have something that looks similar to the illustration shown below. Vss is used for driving the logic circuitry which can be 5 to 7V. In the first example we will control the speed of the motor using a potentiometer and change the rotation direction using a push button. So you will need three output pins on the Arduino micro-controller for each motor. Note: if you have missed any connection and face any Problem, you can watch video given at the end of this Article.

In the video each and every connection is clearly explained. The Arduino is connected to a 5V power bank and the L298N is connected to a 9V battery. Connect 5V and the ground of the IC to 5V and the ground of Arduino, respectively. A common technique for doing this is to use PWM (Pulse Width Modulation). Once again if your stepper motor's power supply is less than 12V, fit the jumper to the module at point 3 which gives you a neat 5V power supply for your Arduino. First, we’ll take a quick look on how the L298N motor driver works. The controls to the L298 are thru the Arduino Pins 6 and 7. Note that the 5 Volts for the L298N board is now being supplied from the Arduino 5 Volt output. How to solve MAX485 heating and stops working problem ? Output A, Output B – To connect two motors. The goal is to design a wemos wifi controlled robot using L298N controller. If you want to control motors using the L293D motor controller, then follow this Tutorial | L293D Motor Driver IC with Arduino. I've swapped out my Arduino Uno for a WeMos D1 Mini. It comes with two separate channels, called A and B, that you can use to drive 2 DC motors, or 1 stepper motor when combined. You can now use the +5V pin at #6 (and the GND pin at #5) to power your Arduino. The L298N module supports up to two motors. Input 1 and Input 2 pins are used to control the direction of Motor 1 is connected to pin 13, pin 12 of the Arduino respectively. The Arduino Uno has 14 digital Input/Output (I/O) pins, six of which are capable of supplying a PWM signal. For example the schematic diagram below shows the setup of a motor to be controlled by the L298N driver and Arduino. The Arduino Uno has 14 digital Input/Output (I/O) pins, six of which are capable of supplying a PWM signal. In this project, we will focus on the more advanced L298N Motor Driver and see Arduino DC Motor Control using L298N Motor Driver using PWM technique. Let's get started! Next, connect L298N module pins IN1, IN2, IN3 and IN4 to Arduino digital pins D8, D9, D10 and D11 respectively. In the video each and every connection is clearly explained. directionControl() – This function spins both motors forward at maximum speed for two seconds.
