Ik wil een eenvoudige 17 button IRzender gebruiken, maar de regel "Serial.println(results.value, HEX) print ook vaak FFFFFFFF.
ik wil alleen maar geldige meldingen zien (in switch).
Wat is er fout?

WHAT DOES THIS PROGRAM:
- The program shows  the HEX code of an IR-sender on the serial monitor

HARDWARE:
-  Arduino Nano
-  IR-sensor module (ouput pin connectod to pin D10 on Nano
-  Simple IR sender (0..9, star, gat, up, down, right, left, OK), i.e 17 buttons

TESTED ON:
IDE 1.8.19 and Arduino Arduino Nano V3

Thanks Jackson, it works but I got many results after only one press.
I added delay(200); before IrReceiver.resume();

Are the results the long press key code ?
