Introduction: SMART HOME AUTOMATION
In present time there are many types of Home Automation Systems available in our market. Most of these are simple home appliances controlling systems like DTMF controlled home Appliances, RF based home appliances controlling, GSM based Home/Office Appliances Control (Home Automation System). This home automation allows the user to turn on or off the lights using ir remote controller.
In this system Arduino is the heart of this system which takes control over whole the system process. Here a ir receiver and transmitter is used for sending and receiving the data through wifi
Step 1: HARDWARE USED
ATMEGA 328p-pu
TSOP (ir receiver)
Relays (12v)
tv remote(any ir remote)
Power supply
Step 2: Installation & Code
Code
#include
int RECV_PIN = 6;
IRrecv irrecv(RECV_PIN);
decode_results results;
void setup()
{
//Serial.begin(9600);
pinMode(9,OUTPUT);
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
digitalWrite(9,HIGH);
irrecv.enableIRIn();
// Start the receiver
}
void loop()
{
if (irrecv.decode(&results))
{
// Serial.println(results.value, HEX);
switch(results.value)
{
case 0xC084:
digitalWrite(2, HIGH);
delay(1000);
break;
case 0xC044:
digitalWrite(2, LOW);
