He used the eXtreme Burner for burning the code. He has used the low cost 28 pin AVR Development Board and the USBasp AVR Programmer by eXtreme Electronics. I will show you how that is done in later tutorials after I introduce you with internal TIMERS of AVR because PWM is generated using timers. PWM or pulse width modulation technique is used to digitally control speed of DC motors. The video is made by Lavin Khandelwal for ma圎mbedded. The speed of DC motor can also be controlled with MCU. This is a simple demonstration of controlling two DC motors using a single L293D IC and a microcontroller.

The code can also be found on pastebin and in the code gallery.Īfter burning the code into your MCU, you will find that the motors rotate in clockwise direction for 0.5s and counter-clockwise direction for 0.5s. If you are new to AVR Studio 5, you can read this post to get started with it. Now open up AVR Studio 5, type the following code and build it. Assuming ATMEGA32, let us connect L293D across PORTC pins (PC0…PC3) as shown in the diagram below. Now let’s generate control signals from the AVR MCU and feed them to the inputs of L293D. Enabling both pins at the same time will drain your battery unnecessarily. Suppose if you need to control only one motor at a time, you need to enable that particular EN pin. M2-A = 0 and M2-B = 1 → M2 moves counter-clockwise.M2-A = 1 and M2-B = 0 → M2 moves clockwise (say).M1-A = 0 and M1-B = 1 → M1 moves counter-clockwise.M1-A = 1 and M1-B = 0 → M1 moves clockwise (say).Now consider the following cases for motor M1:
This IC can drive two brushed DC motors independently, using a wide range of supply voltages, while delivering reasonably high current to the connected DC motors.

An proteus simulation file is also available at the download so that you can check the code on your PC. Also a bar graph Led display indicate the speed of the motor. There are three buttons to control the motor. You can also control the direction of the motor.

The Dc motor is derived by the L298 driver IC. In this way, we can have bidirectional control over two motor. This project gives a speed control of DC motor through PWM method.
