For changing the direction of rotation without reversing the leads of the motor every time, you need to use a special circuit called H-Bridge. This circuit is good for controlling the speed of the motor but not an effective way to change the direction of rotation. gradually increases the speed to peak and then gradually decreases the speed to halt. Using this code, the Arduino will vary the speed of a DC Motor in a fading fashion i.e.
#How to set up the l298n motor driver code
The code for this circuit is given below. The following image shows a simple circuit diagram, where a PWM output from Arduino is given to a MOSFET and the 12V DC Motor is connected through the MOSFET. 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. Now that we have controlled the average voltage that is to be supplied to a DC Motor, how do we apply this voltage to the motor? Here comes the use of Transistor. sum of ON time and OFF time.ĭuty 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. 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. It can drive inductive loads e.g relays, solenoids, motors (DC and stepping motor) etc.Ī DC Motor is the simplest of motors that beginners and hobbyists encounter.

It is a high current dual full-bridge driver which is designed as to accept standard TTL logic levels. Features of L298 motor driver L298N is an integrated circuit multi watt 15 package and capable of giving high voltage. The L298N Module is large in size and will need plenty of space if fitting inside a vehicle. Included, is an easy wiring connection diagram and some start code for quick reference. So this quick how-to guide will help you get going quickly with the L298N Dual H-Bridge DC Motor Driver Module. 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. With this motor driver you can control DC motors, stepper motors, relays and solenoids. The L298N Motor Driver Board is built around the L298 dual full-bridge driver, made by STMicroelectronics. Information about the L298N Motor Driver. 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.
