Arduino IDE code Error with GEMMA v2

[emaxmartino]

Hello guys!
I'm making this "buzzing-mindfulness-bracelet" Beky Stern project with my GEMMA V2, but when I upload the code with ARDUINO IDE, I get these errors:

C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino\WInterrupts.c: In function 'attachInterrupt':

Anyone know how to help me?

My board works fine with other codes, so I don't think a connection problem with the computer.
In fact if I change the code, it loads it fine. It can be a code error?
Thanks a lot!!

That compiled perfectly.
If it works there is no problem.
Hope this helps.

Hi, Yes, it compiles, but it doesn't do its job, it never vibrates. Could it be because of the errors? Thanks

Check your wiring.

I checked and the circuit is exactly like the one in the diagram in the link I posted. Sure enough with this simplified code, it works (hit vibrates):

// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(1, OUTPUT);
pinMode(0, INPUT_PULLUP);
pinMode(2, INPUT_PULLUP);
}

// the loop routine runs over and over again forever:
void loop() {
digitalWrite(1, HIGH); // turn the LED on (HIGH is the voltage level)
delay(250); // wait for a second
digitalWrite(1, LOW); // turn the LED off by making the voltage LOW
delay (3600000); // wait for a second
}

But this code consumes much more battery and for this project it is a fundamental point.
The original script was designed to keep the board in sleep state to save battery... but I can't get it to work
