Project 1 - Controlling a DC motor using PWM and monitoring its Running status

Preeti madam's Embedded system live batch 12

Overview of the Project:

Implement a system on the simulator for controlling a DC motor using L293 motor driver, monitor its status and print the running status of motor on the LCD Display.

Goals:

• Implement a system on simulator for Controlling the DC motor using L293 motor driver.
• Displaying the running status of DC motor on the LCD display.

Key Highlights of the Project:

• The DC motor can be controlled by using L293 motor driver.
• The speed of a DC motor can be controlled by varying its input voltage, for doing this is to use PWM (Pulse Width Modulation).
• L293D IC is a typical Motor Driver IC which allows the DC motor to drive on any direction.

Deliverables of this project:

• Implement the system for controlling DC motor.
• Controlling the speed of the DC motor using PMW.
• Displaying the present running status of DC machine on LCD display.

Expected Outcomes:

• Implement a system on simulator to control a DC motor using PMW
• Monitoring the running status of the DC motor using L293 motor driver which allows the DC motor to drive on any direction.
• Running status i.e. on which direction the DC motor is running is to be displayed on the LCD screen.

Screenshot of simiulation(SimulIDE):

• Pressed the switch at pin C3 for powering the DC Motor.
• Now motor running in clockwise direction.

• Here direction of DC motor changed to anti clock wise by pressing switch at pin D1.

• Increasing the speed of motor by pressing the push button at pin D2.

• Motor is turned off after pressing the switch at pin C3.

Attached the code with comments, HEX and Simul files

Hence implemented the project as per the given instructions.
