What output do you get on the serial monitor?
Which pin did you connect to the pushbutton?
Which board are you using?

Hi Claudio.
Does it stop working with short and long presses or just long presses?

Hi Sara,
Thanks for your interest. I think I had a problem with the pullup resistor. I first removed the resistor and change line 50 in the code to : pinMode(buttonPin, INPUT_PULLUP);
then it worked.
Thanks
