If you want the left motor to rotate in one direction, apply a high pulse to IN1 and a low pulse to IN2. 4) Connect IN2 of the IC to pin 9 of Arduino. Using PWM (Pulse Width Modulation) to control a device is a common practice in embedded systems; for example, you can use it to control the light intensity of a LED or control the speed of a DC motor. Speed control of any motor is always done y Pulse Width Modulation, abbreviated as PWM. 6) Connect SENS A pin of IC to the ground. Here is a wiring diagram for connecting two DC motors to the L298N driver board. Second Design. MOSFET is switched on and off at high frequency voltage and since motor is connected in series with the drain of MOSFET, PWM value of voltage determines the speed of motor. The methods are :i)Open loop control system ii)Closed loop control system f In open loop control, the control value is not dependent on the output or the speed of the motor, whereas in closed loop control the control value is dependent on the speed of the motor. Connect the Arduino through USB and upload the code Open the serial monitor and set the baud rate at 9600 Now type any number from 0 to 9. 11.

Go to the call back function of the Stop Motor button inside the Matlab source code. The speed is related to the variation of the duty cycle of the PWM signal, the DC motor reaches its maximum speed when the duty cycle is equal to 100% . Speed control system is the most common control algorithm used in industry and has been universally accepted in industrial control. If the temperature is less than 25C, then the DC fan will remain off and details will be displayed on the LCD. The First Simulation is named as Remote Control while the second one is named as DC Motor Control. The PWM signal has a fixed frequency of waves with varying duty cycles (between 0% and 100%), so the motor rotation can be regulated gradually using a potentiometer already programmed on the Arduino Uno board. To reverse the direction, reverse the pulses to IN1 and IN2. In this tutorial we will learn that how to make an algorithm for DC Motor Speed Control using Arduino UNO.
