Touchless switch that open a door and switching light bulb.

 Touchless switch that open a door (by servo motor) and switching  light bulb by using three (3) IR sensor 


  • First IR sensor for switching light bulb.
  • Second IR sensor for opening door when you want to inter.
  • Third IR sensor for opening door when you want to move out.

Second IR sensor and Third IR sensor are connected to one pin in microcontroller.

CODES

#include <Servo.h>


const int Switch = 7, LED = 4;

int state = 0, LEDstate=0;


int irSensor1 = 5; // declaring the pin where IR sensor is attached

Servo door; //naming the servo

int pos = 0; // initial position of the servo


void setup() {

  door.attach(12); // pin to which servo is attached

  pinMode(9,OUTPUT);

  pinMode(10,OUTPUT);

  Serial.begin(9600);

  pinMode(irSensor1, INPUT); // setting the pin to take input from the IR sensor

 

  pinMode(Switch, INPUT);

  pinMode(LED, OUTPUT);

  Serial.begin(9600);


}


void loop() {

  int buttonState1 = digitalRead(irSensor1); //reading the input

  Serial.println(buttonState1); 

  if(buttonState1 == 0){ //if an object is detected the value turns 0

    

    pos = 180; //open the door

    door.write(pos);

    digitalWrite(10,HIGH);//turn on indicato

    }

  else{

    pos = 0; // closing the door when no object

    door.write(pos);

    digitalWrite(10,LOW);//turn off indicator

    }

  delay(5000);


  if (state == 0 && digitalRead(Switch) == HIGH) {

    state = 1;

    LEDstate=!LEDstate;

  }

    delay(200);


  if (state == 1 && digitalRead(Switch) == LOW) {   

    state = 0;

  }

    delay(200);


   digitalWrite(LED, LEDstate);

}
