Buona sera,
ho un problema e sono qui a chiedere aiuto.
Vorrei fare uno sketch che riceva codici da telecomandi IR, ma nel contempo possa generare un PWM sul pin D11.
Lo sketch allegato fa un ciclo faading sul led D11 tramite il pwm.
Succede che se abilito gli interrupt (tolgo // rigo 46) il PWM non funziona più.
Suggerimenti?
Molte grazie

This example shows how to fade an LED using the analogWrite() function.
The circuit:
- LED attached from digital pin 9 to ground.
