TV Remote Controlled Servo Motor-Using Arduino!

Greetings!

We use our TV remotes to control the functions of the TV's, but when the TV is not in use, they're absolutely useless. Today, we are going to learn how to add more functionality to ordinary IR based remotes, in this one we shall see how to control servo motors. There are so many (SO MANY) different applications of this project that one can think of. Using the following tutorial, you can make one yourself!

1. Watch the video tutorial-

2. Things you will need-

Note that you may use a different IR receiver other than TSOP1738, if it isn't available. Usually you can find this on websites like amazon and ebay.

3. The circuit diagram!

4. The IR Remote Library

5. The Arduino Code-

Just copy paste this code into your Arduino IDE

#include <IRremote.h>
#include <IRremoteInt.h>

#include <Servo.h>


int RECV_PIN = 11; //IR receiver pin

int gndIR=10; //initialize pin 10

int powerIR=9;//intialize pin 9

IRrecv irrecv(RECV_PIN);


Servo myservo;  // create servo object to control a servo
                // a maximum of eight servo objects can be created

int pos = 0;    // variable to store the servo position


decode_results results;

void setup(){
  irrecv.enableIRIn(); // start the receiver
pinMode(gndIR, OUTPUT);
pinMode(powerIR, OUTPUT);
digitalWrite(gndIR, LOW); // using pin 10 as gnd
digitalWrite(powerIR, 255); // using pin 9 as a 5v power source

  myservo.attach(5); // declaring the servo object

}

void loop() {

 if (irrecv.decode(&results)) {
  if (results.value==0xE0E0D02F ){ //Move the servo to 35 degrees position
 // You've gotto change these hexadecimal values(0xE0E...) to button values corresponding to your remote
 
    myservo.write(35);
    delay(15);

   }
  if (results.value==0xE0E0E01F ){ //move the servo to 170 degrees position
 
    myservo.write(170);
    delay(15);
    }
   if (results.value==0xE0E0A659 ){//add +10 degress to servo position
 if(pos<180){
     pos=pos+10;
    myservo.write(pos);
    delay(15);
    }}
     if (results.value==0xE0E046B9 ){// decrease servo position by 10
       if(pos>0){
  pos=pos-10;
    myservo.write(pos);
    delay(15);
    }}
  irrecv.resume();
 
}
