More duty cycle means more power delivered to the load(the DC motor) and therefore more speed. This duty cycle corresponds to speed of the motor. The user can enter duty cycle value from 0 to 100. After user enters the direction command, we then ask the user to enter the duty cycle. First we ask user to enter the direction which can be either forward, reverse or stop.
HOW TO PWM ON L298N MOTOR DRIVER SERIAL
In the main loop, we ask user to enter the direction and speed using the Arduino IDE serial monitor.
HOW TO PWM ON L298N MOTOR DRIVER DRIVER
This is done by disabling the full H-bridge inside the L298D motor driver viz by sending low signal to the ENA pin. The stop() function stops the motor from rotating. In this way we can use Arduino for DC motor forward reverse direction control. Similarly, for reverse direction we output fast pwm signal from OC0B pin and into the motor and out into the OC0A. This is explained in details with duty cycle formula in the tutorial Programming Arduino Timer 0 in Fast PWM mode. The fast pwm signal then flows from OCR0A into the motor and out into the OC0B. Also in case of forward direction the pin 5 or OC0B is made low. The duty cycle is loaded into the OCR0A register. In the forward() function, we supply Fast PWM signal on pin 6 or OCA0 pin with some duty cycle. Similarly the reverse() is used to rotate the motor in reverse direction with user specified duty cycle. The forward() function is used to rotate the motor in forward direction with user specified duty cycle.

In the above arduino code for dc speed and direction control, we have used two functions called forward() and reverse(). Program for DC motor speed control using Fast PWM with L298N & Arduino //Source:
DC motor speed control Arduino codeīelow is arduino code for DC motor speed and direction control using L298D motor driver. The protection diode for back e.m.f from motor wires due to sudden cutoff of current are connected to the DC motor as shown. The DC motor is connected to OUT1 and OUT2 of the L298N. The digital pin 7 of Arduino is connected to the ENA pin of L298N motor driver. The OCA0 and OCB0 are used by Timer 0 to output Fast PWM. In the above circuit schematic diagram, the Arduino pins 6(OCA0) and 5(OCB0) are connected to IN1 and IN2 of the L298N motor driver respectively. The following picture L298N connected to Arduino PWM pins 5 and 6, the DC motor, the diode protection on a breadboard.
HOW TO PWM ON L298N MOTOR DRIVER HOW TO
The analogWrite() function used with Arduino uses Phase Correct PWM mode which was illustrated in previous tutorials How to use L298N motor driver with Arduino and Arduino L298N DC Motor Speed control with PWM. Although it is adviced to use Phase Correct PWM mode for motor control application, here for sake of illustration we will use Fast PWM mode. Within Fast PWM we can generate inverted and non-inverted Fast PWM signal. We can generate broadly two types of PWM signal with Arduino one of which is Fast PWM and the other is Phase Correct PWM. May not be accurate, so for original content go to Speed and direction control of DC motor using Arduino Fast PWM.Īrduino has six PWM pins out of which 6 and 5 are used by Timer 0. The website has been stealing content without consent from this ee-diary Example arduino code for Fast PWM DC motor control is provided. The output from the L298N is used to drive a simple DC motor. Fast PWM signal is generated on pin 6(OC0A) and pin 5(OC0B) on Arduino using Timer 0 which is fed into the L298N motor driver. To control the DC motor the L298N motor driver is used. In this Arduino Electronics tutorial, DC motor speed and direction control using Fast PWM method is illustrated.
