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

CHALLENGE 5 : PROJECT 1

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.

Program:

#include <stdio.h>

// Function to control the DC motor using L293 motor driver

void controlMotor(int speed, int direction)

{

// Code to control the motor using L293 motor driver

// This function can vary depending on your hardware setup

// Implement the necessary logic to control the motor speed and direction

// For simulation purposes, you can print the speed and direction instead

printf("\nControlling motor: Speed=%d, Direction=%d\n", speed, direction);

}

// Function to display the running status on the LCD display

void displayStatus(int direction)

{

// Code to display the running status on the LCD display

// This function can vary depending on your hardware setup

// For simulation purposes, you can print the direction instead

printf("\nLCD Display: Motor running in direction %d\n", direction);

}

int main()

{

int speed = 50; // Speed of the motor (0-100)

int direction = 1; // Direction of the motor (1: Forward, 0: Reverse)

// Control the motor using the L293 motor driver

controlMotor(speed, direction);

// Display the running status on the LCD display

displayStatus(direction);

return 0;

}

Output:

Controlling motor: Speed=50, Direction=1

LCD Display: Motor running in direction 1

Description of the program:

1. The necessary header file `stdio.h` is included, which provides functions for input and output operations.

2. The `controlMotor` function is defined. This function is responsible for controlling the DC motor using the L293 motor driver. In this example, it is a placeholder function that prints the speed and direction of the motor. You should modify this function to include the actual logic for controlling the motor based on your hardware setup.

3. The `displayStatus` function is defined. This function is responsible for displaying the running status of the motor on the LCD display. Similarly, it is a placeholder function that prints the direction of the motor. Modify this function to suit your hardware setup and display the status on the actual LCD display.

4. The `main` function is the entry point of the program. It initializes the `speed` and `direction` variables, representing the speed and direction of the motor, respectively.

5. The `controlMotor` function is called with the `speed` and `direction` variables as arguments. This simulates the control of the motor using the L293 motor driver. In this example, it prints the speed and direction of the motor to the console.

6. The `displayStatus` function is called with the `direction` variable as an argument. This simulates the display of the running status on the LCD display. In this example, it prints the direction of the motor to the console.

7. The program ends by returning 0, indicating successful execution.
