WORKING WITH IR SENSOR || CONTROLLING LED,BUZZER,SERVO

                                                 WORKING WITH IR-SENSOR

1. IR-SENSOR WITH LED

i. COMPONENTS REQUIRED:

1. ARDUINO UNO

2. IR-SENSOR

3. LED

4. JUMPER WIRES

           ii.  CIRCUIT DIAGRAM

        Iii. SOURCE CODE

code 1: Analog pins

int led = 13;
int sensor;

void setup() {
pinMode(A0, INPUT); // analog pin
pinMode(led, OUTPUT);
}

void loop() {
sensor = digitalRead(A0);//reading analog pin A0

if(sensor == LOW){
  digitalWrite(led, HIGH);//led on
}
else{
  digitalWrite(led, LOW);//led off
}
}

code 2: Digital pins

int led = 13;
int sensor;

void setup() {
pinMode(5, INPUT); // digital  pin
pinMode(led, OUTPUT);
}

void loop() {
sensor = digitalRead(5);//reading digital pin 5

if(sensor == LOW){
  digitalWrite(led, HIGH);//led on
}
else{
  digitalWrite(led, LOW);//led off
}
}

2. IR-SENSOR WITH SERVO

i. COMPONENTS REQUIRED:

5. ARDUINO UNO

6. IR-SENSOR

7. SERVO

8. JUMPER WIRES

           ii.  CIRCUIT DIAGRAM

 iii. SOURCE CODE

code 1: Analog pins

#include<Servo.h>

Servo myservo;
int sensor;

void setup() {
pinMode(A0, INPUT); // analog pin A0
myservo.attach(10); // servo connected to pin 10
}

void loop() {
sensor = digitalRead(A0);//reading analog pin A0

if(sensor == LOW){
myservo.write(180); // rotate 180 degrees
}
else{
myservo.write(0);  // rotate return back to 0 degrees
}
}

code 2: Digital pins

#include<Servo.h>

Servo myservo;
int sensor;

void setup() {
pinMode(8, INPUT); // digital pin 8
myservo.attach(10); // servo connected to pin 10
}

void loop() {
sensor = digitalRead(8);//reading analog pin 8

if(sensor == LOW){
myservo.write(180); // rotate 180 degrees
}
else{
myservo.write(0);  // rotate return back to 0 degrees
}

} 

C. IR-SENSOR WITH BUZZER AND SERVO

CIRCUIT:

CODE:

#include<Servo.h>

Servo myservo; 

int sensor;

int BUZZER = 10;

void setup() {

pinMode(A0, INPUT); // ANALOG pin A0

myservo.attach(6); // servo connected to pin 6

pinMode(BUZZER, OUTPUT); // DIITAL pin 10

}

void loop() {

digitalWrite(BUZZER, LOW);  

sensor = digitalRead(8);//reading analog pin 8

if(sensor == LOW){

myservo.write(180); // rotate 180 degrees

digitalWrite(BUZZER, HIGH);

delay(1000);//BUZZ FOR 1 SECOND

}

else{

myservo.write(0);  // rotate return back to 0 degrees

digitalWrite(BUZZER, HIGH);

delay(1000);//BUZZ FOR 1 SECOND

}

}
