Story

So, I found this little Fan (it should be at least 10 years old), which was powered by some buttons and I had to get up from my bed/chair/whatever I was sitting on just to turn it on/off or to change speed (it has 3 speed).

So I came up with this idea of turning it off/on and changing speed with a simple IR Remote, obtaining a lot of comfort during hot summer days and nights.

So, I think that was a very nice idea and everything works properly.

Obviosuly, you can use that approach for every household appliance you have in your home, hope you will find it useful!

Have a nice day :)

Just one thing: YOU'RE WORKING WITH 220V, SO BE VERY VERY VERY VERY VERY CAREFUL BECAUSE YOU COULD SERIOUSLY HARM YOURSELF.

I used a 220V to 12V inverter to power Arduino directly from 220V.

It fit almost perfectly!

Code

#include <IRremoteInt.h>

#include <IRremote.h> // use the library
int receiver = 11; // pin 1 of IR receiver to Arduino digital pin 11
IRrecv irrecv(receiver); // create instance of 'irrecv'
decode_results results;

void setup()
{
  Serial.begin(9600); // for serial monitor output
  irrecv.enableIRIn(); // Start the receiver
  pinMode(5, OUTPUT); //IN1 of first Relay
  pinMode(6, OUTPUT); //IN2 of first Relay
  pinMode(7, OUTPUT); //IN1 of second Relay
}
void loop()
{
  if (irrecv.decode(&results)) // have we received an IR signal?
  {
    Serial.println(results.value, HEX); // display it on serial monitor in hexadecimal
    irrecv.resume();// receive the next value
  }
 
 //Check if other Relays are OFF before turning ON the one selected.
  if (results.value == 0x"YOURCODE1"){ 
    if (digitalRead(6) == LOW && digitalRead(7) == LOW) {
    digitalWrite(5, HIGH); 
  }
    else if(digitalRead(6) == HIGH || digitalRead(7) == HIGH) {
      digitalWrite(6, LOW);
      digitalWrite(7, LOW);
      delay(1000); //Wait a sec just to be sure of not causing a short circuit
      digitalWrite(5, HIGH);
    }
  }
  
 if ( results.value == 0x"YOURCODE2"){ 
  if (digitalRead(5) == LOW && digitalRead(7) == LOW) {
    digitalWrite(6, HIGH); 
  }
  else if(digitalRead(5) == HIGH || digitalRead(7) == HIGH) {
      digitalWrite(5, LOW);
      digitalWrite(7, LOW);
      delay(1000);
      digitalWrite(6, HIGH);
    }
 }  

 if ( results.value == 0x"YOURCODE3"){ 
  if (digitalRead(5) == LOW && digitalRead(6) == LOW) {
    digitalWrite(7, HIGH); 
  }
  else if(digitalRead(5) == HIGH || digitalRead(6) == HIGH) {
      digitalWrite(5, LOW);
      digitalWrite(6, LOW);
      delay(1000);
      digitalWrite(7, HIGH);
    }
 }  

// Put here your code for turning off the Fan
 if ( results.value == 0x"YOURCODE4"){
  digitalWrite(5, LOW);
  digitalWrite(6, LOW);
  digitalWrite(7, LOW);
 }
