If the user enters either f or r, then the speed is asked. The user either enters f, r or s for forward direction, reverse direction or to stop the motor.
#L298n motor driver ic serial
The speed and direction are asked to users on Arduino IDE serial monitor. In the above arduino pwm motor control example code, user are asked for the direction first. Serial.println("Enter Reverse Speed(0 to 255):") Serial.println("Enter Forward Speed(0 to 255):") Serial.println("\nEnter Direction(f=forward,r=reverse,s=stop):") Program for DC motor speed control using PWM with L298N & Arduino Here we have applied PWM signal during the forward and reverse direction. The implementation of the above circuit schematic is shown below.Īrduino code for DC motor speed control with PWM using L298Nīelow is Arduino code for DC motor speed control using L298N. Here we have used only +5V to drive simple DC motor. This Vs pin should be connected to the higher voltage source in theĪbove L298N motor driver Schematic if higher rated DC motor is used. Is connected to the +5V supply which is used to drive the DC motor.

The Vss(or Vcc) pin of the L298N is connected to the +5V logic Sensing which are simply connected to ground in this example tutorial. Shown in the schematic diagram to avoid any unwanted reverse current Four 1N4004(or use 1N4001) diodes are connected as The OUT1 and OUT2 of the L298N are connected to two wires By sending LOWįrom the Arduino we can switch off the first dual H-bridge of the L298NĪnd by sending HIGH from Arduino we can turn on the first dual H-bridge L298N is connected to the digital pin 8 of the Arduino. The speed is controlled by sending PWM signal onto the pin 10 or pin 9. The direction is controlled by making pin 10 high and pin 9 low and vice versa. By sending signal from the Arduino on these L298N pinsĬontrols the direction of the motor rotation. In the above circuit schematic drawing, the inputs of L298N motor driver IN1(pin 5) and IN2(pin 7) are connected to the pin 10 and pin 9 of Arduino
