Project 1 - Controlling a DC motor using PWM and monitoring its Running status
PROJECT OVERVIEW:-
We are going to implement a system for controlling a DC motor using the L293 driver and Monitor and print the running status of motor in the LCD screen by using the SimulIDE.
GOALS:-
As we are implement a system on simulator for controlling the DC motor using L293 motor driver.
By using the L293 motor driver we are not going to give the motor supply current and driver supply into driver pins as we are going to do in hardware implementations.
When the motor is running through the L293 motor driver we are using the different status of DC motor. So, we need to display the running status of the motor in the LCD screen.
KEY HIGHLIGHTS OF THE PROJECT:-
By using the L293 motor driver we can control the DC motor.
In 293 Driver pins 1A & 2A are the terminals decide the direction of rotation of the motor, pins 1y & 2y terminals are to be connected to the terminals of motor and Enable pins are used to control the speed of the dc motor.
If we apply the PWM signal to the enable pins then the motor driver can control the speed of the motor.
Also when we give the opposite signal thee DC motor will rotate in reverse direction also.
DELIVERABLES OF THE PROJECT:-
Here we are implementing the system for the controlling of the DC Motor. By using the atmega32 controller, hd44780-54, L293 motor driver and DC motor in the SimulIDE software.
Controlling speed of the dc motor can be done by using PWM method. Mainly speed of a motor is directly affected by 3 factors Load, Voltage and Current.
For a given laod we can be maintain a steady speed by using a method called PWM. By varying the width of the pulse applied to the dc motor we can vary the power applied to the dc motor and increase or decrease the motor speed.
We are displaying the running status of the DC motor on the hd44780-54 LCD. Weather it is running in clockwise or Anti-clockwise direction or motor is off.
