Description
IR Remote for Fan
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.
Code
Remote.ino
C/C++
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. // 0x"YOURCODE1" will turn into something like // 0xABCDEFX after reading the remote value // Same for YOURCODE2/3/4 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); } }
Decoder.ino
C/C++
