Quiz-Taster mit Arduino

Für den Schulunterricht habe ich diesen Quiz-Taster entwickelt. In seinem Inneren werkelt ein Arduino:

 

 

Das verwendete sketch ist sicher verbesserungswürdig, aber es tut seinen Dienst: 

 

[code]
#include "pitches.h"

int Taster1 = 13;
int Lampe1 = 12;
int Taster2 = 7;
int Lampe2 = 6;

int myCounter1 = 0;
int myCounter2 = 0;
int myCounter3 = 0;
int myCounter4 = 0;

void setup() {

pinMode (Taster1, INPUT);
pinMode (Lampe1, OUTPUT);
pinMode (Taster2, INPUT);
pinMode (Lampe2, OUTPUT);

digitalWrite (Lampe1, HIGH);
delay (250);
digitalWrite (Lampe1, LOW);
digitalWrite (Lampe2, HIGH);
delay (250);
digitalWrite (Lampe2, LOW);
digitalWrite (Lampe1, HIGH);
delay (250);
digitalWrite (Lampe1, LOW);
digitalWrite (Lampe2, HIGH);
delay (250);
digitalWrite (Lampe2, LOW);

int melody[] = {
  NOTE_C4, NOTE_G3, NOTE_G3, NOTE_A3, NOTE_G3, 0, NOTE_B3, NOTE_C4
};

int noteDurations[] = {
  4, 8, 8, 4, 4, 4, 4, 4
};

// iterate over the notes of the melody:
  for (int thisNote = 0; thisNote < 8; thisNote++) {

    // to calculate the note duration, take one second divided by the note type.
    //e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.
    int noteDuration = 1000 / noteDurations[thisNote];
    tone(8, melody[thisNote], noteDuration);

    // to distinguish the notes, set a minimum time between them.
    // the note's duration + 30% seems to work well:
    int pauseBetweenNotes = noteDuration * 1.30;
    delay(pauseBetweenNotes);
    // stop the tone playing:
    noTone(8);
}}

void loop() {

if (digitalRead (Taster1) == LOW)
   {digitalWrite (Lampe1, LOW);
   myCounter1 = 0;
   myCounter4 = 0;}
 
  if ((digitalRead (Taster1) == HIGH) && ((myCounter3) == 0))
  {digitalWrite (Lampe1, HIGH);
  if ((myCounter1) == 0) {tone (8, 300, 1000);}
  myCounter1 = 1;
  myCounter4 = 1;
  delay (250);}

   
if (digitalRead (Taster2) == LOW)
  {digitalWrite (Lampe2, LOW);
  myCounter2 = 0;
  myCounter3 = 0;}

  if ((digitalRead (Taster2) == HIGH) && ((myCounter4) == 0))
  { digitalWrite (Lampe2, HIGH);
  {if ((myCounter2) == 0) {tone (8, 600, 1000);}
  myCounter2 = 1;
  myCounter3 = 1;
  delay (250);}
  }}
