Control AC load with TV Remote by using Arduino | Fair Electro
How we can control our room switch board with TV remote? Hello friends today we will make circuit by using Arduino UNO R3 which control AC load of our room. I use IR sensor and TV remote.

code:
#include IRremote.h // ada angular brackets
#define irPin 3
IRrecv irrecv(irPin);
decode_results results;
#define r1 5
int relay1 = LOW;
#define r2 6
int relay2 = LOW;
#define r3 7
int relay3 = LOW;
#define r4 8
int relay4 = LOW;
void setup()
{
Serial.begin(9600);
irrecv.enableIRIn();
pinMode(r1, OUTPUT);
pinMode(r2, OUTPUT);
pinMode(r3, OUTPUT);
pinMode(r4, OUTPUT);
}
void loop()
{
if (irrecv.decode(&results))
{
Serial.print(results.value, HEX);
Serial.print(" - ");
Serial.println(results.value);
switch (results.value)
{
case 284158740:
digitalWrite(r1,0);
digitalWrite(r2,0); //all off
digitalWrite(r3,0);
digitalWrite(r4,0);
delay(250);
break;
case 284141910:
relay1 = ~ relay1;
digitalWrite(r1,relay1);
delay(250);
break;
case 284137830:
relay2 = ~ relay2;
digitalWrite(r2,relay2);
delay(250);
break;
case 284145990:
relay3 = ~ relay3;
digitalWrite(r3,relay3);
delay(250);
break;
case 284126100:
relay4 = ~ relay4;
digitalWrite(r4,relay4);
delay(250);
break;
}
irrecv.resume();
}
