Synopsis

This circuit will open and close the curtain of your  home and office just by pushing a switch. So , with the help of this unique circuit , we do not need to move from one place to open and close the curtain.

1)List of hardware ,software and components

Hardware

      i)DC motor

      ii)Microcontroller board

Software

    i)MPLAB version 8.3

   ii)Hi-Tech C compiler version 2.3

   iii)Proteus Professional

2)The circuit diagram for this project

    

3)The coding

#include<htc.h>

void delay(unsigned long);

void forward(void);

void reverse(void);

void stop(void);

void main()

{

            TRISB=0b00000011;

            PORTB=0b00000000;

            TRISC=0b00000000;

            PORTC=0b00000000;

            while(1)

            {

                        if(S3==0&&S4==1) //press sw1, move clockwise

                        {

                                    forward();

                        }

                       

                        else if(S3==1&&S4==0) //press sw2, move counter clockwise

                        {

                                    reverse();

                        }

                       

                        else

                        {

                        stop(); //stop the motor

                        }

            }

}

void forward(void)

{

            MOTOR_1=0;

            MOTOR_2=1;

            PWM=1;

}

void reverse(void)

{

            MOTOR_1=1;

            MOTOR_2=0;

            PWM=1;

}

void stop(void)

{

            MOTOR_1=0;

            MOTOR_2=0;

            PWM=0;

}

void delay(unsigned long)

{

            unsigned char i;

            for (i=0xDE;i!=0;i--)

            {

                        unsigned char j;

                        for (j=0x50;j!=0;j--)

                        {

                                    unsigned char k;

                                    for (k=0xC;k!=0;k--)

                                    {

                                    }

                        }

            }

}

4)The video below showing the circuit connection and the and the result of the project

5)Conclusion

From the presentation day that we have done, it will improve our soft skills and also creativity in building the project. When we work later on, we can use this skill in our field of  IT.
