#Arduino l298n motor driver driver
Since the L298N Motor Driver IC is a dual full bridge driver IC, you can control two motors at the same time with individual inputs.
The following image shows the Pin Diagram of the L298N IC in Multiwatt Package (Multi Leaded Power Package). The logic levels of L298N IC are compatible with standard TTL and IC can be used to drive different inductive loads like DC Motors, Stepper Motors, Relay, etc. speed and direction of rotation using a combination of PWM Signal and L298N (HBridge).Ī Brief Note on L298N Motor Driver: L298N Motor Driver IC is a 15-lead high voltage, high current Motor Driver IC with two full bridge drivers. In the Arduino DC Motor Control using L298N Project, we will control both the functionalities of a simple DC Motor i.e. You need few additional components for this project and the complete list is given below. The PWM Signal from any source like Arduino in this example, can be given to the gate of a MOSFET and depending on the duty cycle of the PWM Signal, the speed of the DC Motor will vary.Īrduino DC Motor Control using L298N: We will now see a simple circuit where we control the speed and direction of a DC Motor using Arduino and L298N IC. Duty Cycle is usually expressed in percent and the following figure represents different PWM Signals of a 12V supply with different duty cycles of 0%, 25%, 50%, 75% and 100% respectively. Duty Cycle of a PWM Signal is nothing but the ratio of the time for which the signal is ON or HIGH to the total time period of the signal i.e. Now, the average voltage applied to the DC Motor will depend on what is called as the Duty Cycle of the PWM Signal. The frequency of this switching will be in the order of few tens of kilo Hertz. Speed Control of DC Motor using PWM: Using PWM technique, the average value of the voltage that is applied to the DC Motor is controlled by turning the power on and off at a very high rate. The Pulse Width Modulation or PWM signal generated by this technique will allow us to control the average voltage that is being delivered to the DC Motor. If you want to control the speed of rotation of a simple DC Motor, then there is a technique called PWM DC Motor Control. reverse the polarity, the motor will rotate in reverse direction.
It is very simple to operate: connect the two leads of the motor to the two terminals of a battery and voila! Your motor starts rotating. Overview: A DC Motor is the simplest of motors that beginners and hobbyists encounter. There are different ways to control a DC Motor but the Arduino DC Motor Control using L298N Motor Driver is becoming quite popular for many reasons.
