IRRemote library conflicts with tone() function

Using Arduino Programming Questions

You have a problem :wink: There are limited resources on a microcontroller. Get an Arduino that has more timers (if you currently use an Uno/Nano/Mini, 32U4 based or a Mega provide extra timers).

Or use something else instead of the tone library; switching a pin on and off at a certain 'rate' gives you a tone. An extremely simple example

void loop()
{
  digitalWrite(tonePin, LOW);
  delay(10);
  digitalWrite(tonePin, HIGH);
  delay(10);
}

gives a tone of roughly 50 Hz. There are limitations to this (even if you use a millis / micros based approach) so your mileage will vary :wink:
