ARDUINO IR REMOTE (USE YOUR OLD REMOTE TO CONTROLL HOME APPLIANCES)

In this project you can choose any remote or a TV remote which you are using and you will notice that some keys are useless for your tv for that you can use that keys for controlling the home appliences like powering your TV,FAN,LIGHTS etc...
you need to follow the simple procedure from the video so that you can record hexa values for that particular key and put into the program of the arduino

Step 1: WATCH THE VIDEO

Step 2: THINGS NEEDED

The things needed for the following project are

1.ARDUINO UNO OR CLONE

2.IR RECIVER

3.ANY OLD REMOTE

4.RELAY MODULE

5.JUMPER WIRES

6.ARDUINO IDE

7.SOME LED'S

IF YOU WANT TO MAKE A RELAY MODULE BY YOURSELF YOU COULD NEED (OPTIONAL)

1.RELAY

2.BC547 TRANSISTOR

3. 1K OHM RESISTOR

4.COPPER DOT PCB

Step 3: RECIVING THE IR CODE FROM REMOTE BUTTON

This is the test to recieve the hexadecimal code of the remote button

1.install the ir remote library form the following link in the arduino / library folder

https://github.com/z3t0/Arduino-IRremote

if you already have the library installed follow the next step

2.open the arduino ide and open example/IRrecvDemo sketch into the arduino ide

3.upload the code to the arduino.

4.now connect the ir reciver to the arduino as shown in the video.

5.open the serial monitor in the arduino ide.

6.press any button on the remote and note the hexadecimal value of the button pressed

7.now you have the code of the button you can follow the next step

Step 4: MODIFYING THE ARDUINO CODE

YOU COULD USE THE FOLLOWING SKETCH TO MAKE 1 APPLICATION CONTROL

#include<IRremote.h>

int RECV_PIN = 11;

int state;

int led=13;

IRrecv irrecv(RECV_PIN);

decode_results results;

void setup()

{

Serial.begin(9600);

pinMode(led,OUTPUT);

state=0;

irrecv.enableIRIn(); // Start the receiver

}

void loop()

{

if (irrecv.decode(&results))

{

if(results.value==(0xpaste your hexadecimal code for example "0xF730F4" )

{

if(state==0);

{

digitalWrite(led,HIGH);

state=1;

}

else

{

digitalWrite(led,LOW);

state=0;

}

Serial.println(results.value, HEX);

irrecv.resume(); // Receive the next value

}

delay(100);

}

AFTER UPLOADING THE FOLLOWING SKETCH TO THE ARDUINO CONNECT THE LED TO THE PIN 13 OF ARDUINO AND IR RECIVER OUTPUT TO 11 PIN OF ARDUINO TEST IT USING THE SAME REMOTE BUTTON WHOSE HEXADECIMAL CODE YOU HAVE COPIED.

IF YOU WANT TO INCREASE THE NUMBER OF CONTROLS

THEN YOU CAN USE THE MORE NUMBER OF DIFFERENT INT FUCTIONS FOR EXAMPLE

int light=13;

int fan=12;

int tablefan=11;

int tubelight=10;

and similarly the pinmode in the void setup as

pinMode(light,OUTPUT);

etc..

similarly in the void loop section include the hexadecimal code of the button and repeat the loop as many time your number of controls

Step 5: ADDING RELAY MODULE

YOU COULD BUY A 5V RELAY MODULE FROM ONLINE AND CONNECT IN THE FOLLOWING WAY

ARDUINO RELAY MODULE

+5V------------------------->+5V

GND------------------------>GND

13--------------------------->IN1

12--------------------------->IN2

11--------------------------->IN3

10--------------------------->IN4

AND THE SAME PROCESS REPEATS FOR THE NUMBER OF CONTROLS YOU HAVE

CONNECT THE NEUTRAL WIRE OF THE MAINS POWER SUPPLY(AC) TO THE NORMALLY OPEN SIDE OF THE RELAY AND THE LINE WIRE TO HOME APPLIANCE(BULB) THE THE SECOND WIRE FROM THE BULB WILL GO TO THE CENTER PIN OF THE RELAY

[ WARNING:: PLEASE DO NOT TRY TO PLAY WITH THE 240V AC POWER SUPPLY THAT CAN KILL YOU IMMEDIATELY ]

BEFORE CONNECTING THE RELAY MODULE DIRECTLY TO AC SOURCE CHECK THE CONNECTIONS TWICE AND MAKE SURE EVERYTHING IS CORRECT
