Time isn't working

 if (estadobotao==0) {
    
    //digitalWrite(led,HIGH);
//    delay(3000);
 }
 else {
    digitalWrite(led,LOW);  //Botão não pressionado, apaga o led.    

    wtempo=millis(); //tempo em milisegundos 

 }    
if (millis()-wtempo > 3000) {        // inicia o modo de programação
    programa();
 }

estadobotao is digitalRead() of botao (pin 3) which was set to INPUT_PULLUP.

So, if pressed, do nothing.

If not pressed set wtemp= millis().

I don't see how the next statement can ever be true to call programa().

EDIT:

I am wrong. If you hold the button down for longer than three seconds, I think you will enter programa(). Can you get some serial output to help you debug? Are you actually setting the alarms[] correctly in programa()?
