Can I connect more than one IR receiver to an Arduino Uno?

Question

I want to use #include <IRremote.h> to receive information from an infrared remote control. It works perfectly with one IR receiver.

But I want to put three or four IR receivers:

IRrecv irrecv6(pin6);
IRrecv irrecv7(pin7);
IRrecv irrecv8(pin8);
IRrecv irrecv9(pin9);
IRrecv irrecv10(pin10);

And:

void setup() {
 Serial.begin(9600);
 irrecv6.enableIRIn(); // Start the receiver
 irrecv7.enableIRIn(); // Start the receiver
 irrecv8.enableIRIn(); // Start the receiver
 irrecv9.enableIRIn(); // Start the receiver
 irrecv10.enableIRIn(); // Start the receiver
}

Inside the loop function, I am checking each pin to see if there is any data received. But only the last pin (which means pin 10 above) is receiving the data and others are not.

• jsotola: you can connect multiple receivers, but why?
• Nijat2018: But always only one of them, which is initialized last, is receiving the Data.
• Gerben: @jsotola you could use it to get a very coarse sense of the direction the signal came from.
• Sanaullah Kayani: did you find the solution, because i also want to put 4 ir receiver on Arduino in my fyp. if you have a solution plz help mee.
• gerivega: Try my link github.com/gerivega/Arduino-IRremote I wanted to do the same thing. I modified the latest library to incorporate the changes done by a previous programmer neco777.

Answer 1

That library only supports one IR receiver at a time. Try this fork that seems to have added multiple receivers support.

Answer 2

Just add some delay between irrecv.decode()s and everything will work just fine.
