PROBLEMA [CODICE ARDUINO] Aiuto urgente

[Reeaver]

Salve a tutti

sto facendo un progetto con Arduino che dovrebbe funzionare nel seguente modo:

1. Alla breadboard sono collegati 4 pulsanti
2. Ci sono anche due led
3. Infine c'è un sensore PIR

Vorrei che una volta che il sensore ha rilevato un movimento accenda uno dei led, lo mantenga acceso e che l'utente abbia la possibilità di inserire un determinato codice che fa accendere l'altro LED (spegnendo il primo).

Il codice è questo:

const int button1 = 8; //first button is on pin 8
const int button2 = 9; //second is on pin 9
const int button3 = 10; //third is pin 10
const int button4 = 11; //fourth is pin 11
const int redLed = 12; //red LED is on pin 4
const int greenLed = 4; //green LED is pin 12
int inputPin = 2;               // choose the input pin (for PIR sensor)
int pirState = LOW;             // we start, assuming no motion detected
int val = 0;                    // variable for reading the pin status


int code[] = {2,3,1,4}; //the desired code is entered in this array,
                        //separated by commas

int entered[4]; //create a new empty array for the code entered by
                //the user (has 4 elements)

void setup(){ //run once at sketch startup
  Serial.begin(9600); //begin Serial

  pinMode(button1, INPUT); //button 1 is an input
  pinMode(button2, INPUT); //button 2 is an input
  pinMode(button3, INPUT); //button 3 is an input
  pinMode(button4, INPUT); //button 4 is an input
  pinMode(redLed, OUTPUT); //the red LED is an output
  pinMode(greenLed, OUTPUT); // the green LED is an output
  pinMode(inputPin, INPUT);     // declare sensor as input
  pinMode(inputPin, INPUT);  // read input value
  setupLights(); //run the setupLights routine
  setupLights(); //run it again
  delay(650); //delay (only for effect, :P not needed)
  digitalWrite(redLed, HIGH); //turn the red LED on
  for (int i = 0; i < 4;i++){ //work through numbers 0-3
    Serial.println(code[i]); //print each digit of the code
    Serial.println(entered[i]); //print each element of the entered[]
                                //array (this was for me to check that it
                                //started at 0
  }
  
}

void checkEntered1(int button /* define the 1,2,3 or 4 as an integer called button */){ //check the first element of the entered[] array
  if (entered[0] != 0){ //if it is not a zero, i.e. it has already been inputted
    checkEntered2(button); //move on to checkEntered2, passing it "button"
  }
  
  else if(entered[0] == 0){ //if it is zero, i.e. if it hasn't been defined with a button yet
    entered[0] = button; //set the first element as the button that has been pressed
    Serial.print("1: ");Serial.println(entered[0]); //for debugging
  }
  
}


void loop();
  val = digitalRead(inputPin);  // read input value
  if (val == HIGH) {            // check if the input is HIGH
    digitalWrite(redLed, HIGH);  // turn LED ON
    delay(150);

    
    if (pirState == LOW) {
      // we have just turned on
      Serial.println("Motion detected!");
      // We only want to print on the output change, not state
      pirState = HIGH;
    }
  } else {
      digitalWrite(redLed, HIGH); // turn LED OFF
      if (pirState == HIGH){
      // we have just turned off
      Serial.println("Motion ended!");
      // We only want to print on the output change, not state
      pirState = LOW;
    }
  }
  

void checkEntered2(int button){ //check the second element of the entered[] array
  if (entered[1] != 0){ //if it is not a zero, i.e. it has already been inputted
    checkEntered3(button); //move on to checkEntered3, passing it "button"
  }
  
  else if(entered[1] == 0){ //if it is zero, i.e. if it hasn't been defined with a button yet
    entered[1] = button; //set the second element as the button that has been pressed
    Serial.print("2: ");Serial.println(entered[1]); //for debugging
  }
  
}

void checkEntered3(int button){  //check the third element of the entered[] array
  if (entered[2] != 0){ //if it is not a zero, i.e. it has already been inputted
    checkEntered4(button); //move on to checkEntered4, passing it "button"
  }
  
  else if (entered[2] == 0){ //if it is zero, i.e. if it hasn't been defined with a button yet
    entered[2] = button; //set the third element as the button that has been pressed
    Serial.print("3: ");Serial.println(entered[2]); //for debugging
  }
  
}

void checkEntered4(int button){ //check the fourth element of the entered[] array
  if (entered[3] == 0){ //if it is zero, i.e. if it hasn't been defined with a button yet
    entered[3] = button; //set the final element as the button that has been pressed
    Serial.print("4: ");Serial.println(entered[3]); //for debugging
    delay(100); //allow time for processing
    compareCode(); //call the compareCode function
  }
}

void compareCode(){ //checks if the code entered is correct by comparing the code[] array with the entered[] array
  for (int i = 0; i<4;i++){ //these three lines are for debugging
    Serial.write(entered[i]);
  }
  if ((entered[0]==code[0]) && (entered[1]==code[1]) && (entered[2]==code[2]) && (entered[3]==code[3])){ //if all the elements of each array are equal
    digitalWrite(redLed, LOW); // turn the red LED off
    digitalWrite(greenLed, HIGH); //turn the green LED on
    delay(100); //wait for a bit
    digitalWrite(greenLed, LOW); //turn the green LED off
    delay(100); //wait for a bit
    digitalWrite(greenLed, HIGH); //turn the green LED on
    delay(100); //wait for a bit
    digitalWrite(greenLed, LOW);  //turn the green LED off
    delay(100); //wait for a bit
    digitalWrite(greenLed, HIGH); //turn the green LED on
    loop(); //return to loop() (not really necessary)
  }
  
  else { //if you (or the intruder) get the code wrong
    flash(); //call the flash function
    for (int i = 0; i < 4; i++){ //this next loop is for debugging
      entered[i] = 0;
      Serial.println(entered[i]);
    }
  }
}

void flash(){ // this is basically the blink example, look at that for an explantion of this, I wont insult your intelligence... oh wait, I already did that earlier when explaining the green LED flashing... sorry 'bout that
  digitalWrite(redLed, LOW);
  delay(250);
  digitalWrite(redLed, HIGH);
  delay(250);
  digitalWrite(redLed, LOW);
  delay(250);
  digitalWrite(redLed, HIGH);
  delay(250);
  digitalWrite(redLed, LOW);
  delay(250);
  digitalWrite(redLed, HIGH);
  delay(250);
  digitalWrite(redLed, LOW);
  delay(250);
  digitalWrite(redLed, HIGH);
  delay(250);
}

void setupLights(){ // a funky display run at reset
  digitalWrite(redLed, HIGH); //turn both
  digitalWrite(greenLed, HIGH); //LEDs on
  delay(75); //wait
  digitalWrite(redLed, LOW); //turn them
  digitalWrite(greenLed, LOW); //off again
  delay(75); //wait
}


void loop2(){ //run repeatedly
  if (digitalRead(button1) == HIGH){ //if button1 is pressed
    checkEntered1(1); //call checkEntered and pass it a 1
    delay(250);//wait, needed for correct functioning, otherwise
               //buttons are deemed to be pressed more than once
  }
  else if (digitalRead(button2) == HIGH){ //if button2 is pressed
    checkEntered1(2); //call checkEntered1 and pass it a 2
    delay(250); //wait
  }
  else if (digitalRead(button3) == HIGH){ //if button3 is pressed
    checkEntered1(3); //call checkEntered1 and pass it a 3
    delay(250); //wait
  }
  else if (digitalRead(button4) == HIGH){ //if button4 is pressed
    checkEntered1(4); //call checkEntered1 and pass it a 4
    delay(250); //wait
  }
}

Mi da purtroppo errore "exit status 1 'val' does not name a type". Ho già sistemato alcuni errori ma con questo non ne vengo a capo (eppure ho la sensazione che sarà una cavolata...).
Mi serve per un esame che devo sostenere oggi. Ogni suggerimento è ben accetto.

Grazie
EDIT: RISOLTOOO !


Se qualcuno è interessato me lo faccia sapere che posto il progetto !
