Suonerie Natalizie arduino led

Continua il progetto delle “suonerie natalizie” con l’aggiunta dei led che si accendono in funzione della musica che arduino sta eseguendo: “Suonerie Natalizie arduino led”

Le suonerie e la spiegazione dello sketch la trovi nel primo articolo.

In questo articolo trovi lo schema dei collegamenti per i led e la descrizioni delle parti dello sketch che ho aggiunto rispetto al progetto senza le luci a led.

I collegamenti per le suonerie natalizie arduino led

Il collegamento dello speaker è il medesimo che già conosci:

a cui ho aggiunto 7 led ad alta luminosità connessi ad una resistenza da 470ohm sul Gnd comune a tutti i led ed arduino:

lo schema che puoi seguire è il seguente:

ai pin 2,3,4,5,6,7,8 sono connessi i 7 led, avrai già compreso che i led rappresentano le note per cui nello sketch dovrai associare a ciascuna nota da eseguire un led corrispondente, indipendentemente dall’ottava su cui suonerà la nota.

Lato arduino i collegamenti dei led li puoi seguire qui:

sono comunque semplici in quanto ogni led è collegato ad un singolo pin.

Lo sketch del progetto

Lo sketch delle suonerie natalizie arduino led è sostanzialmente identico a quello descritto nell’articolo “Suonerie Natalizie arduno” a cui ho aggiunto alcune linee per la gestione i 7 led.

mi soffermo dulle parti di codice aggiunte:

byte p2 = 2;
byte p3 = 3;
byte p4 = 4;
byte p5 = 5;
byte p6 = 6;
byte p7 = 7;
byte p8 = 8;

byte contatore = 0;
byte current_pin = 0;

alle linee 05-11: definisci le variabili in cui memorizzi i valori dei pin per i 7 led che vuoi si accendano a tempo di musica;

linea 14: definisci una variabile il cui valore ad ogni ciclo di loop() assume il valore del pin corrispondente alla nota emessa dallo speaker;

    digitalWrite(p2,LOW);
    digitalWrite(p3,LOW);
    digitalWrite(p4,LOW);
    digitalWrite(p5,LOW);
    digitalWrite(p6,LOW);
    digitalWrite(p7,LOW);
    digitalWrite(p8,LOW);

alle linee 146-152: assegna a ciascun pin a cui è connesso un led un valore LOW ossia spegni tutti i led ad ogni ciclo di loop();

    switch(*p) {
      case 'c':
        note = 1;
        current_pin = p2;
        break;
      case 'd':
        note = 3;
        current_pin = p3;
        break;
      case 'e':
        note = 5;
        current_pin = p4;
        break;
      case 'f':
        note = 6;
        current_pin = p5;
        break;
      case 'g':
        note = 8;
        current_pin = p6;
        break;
      case 'a':
        note = 10;
        current_pin = p7;
        break;
      case 'b':
        note = 12;
        current_pin = p8;
        break;
      case 'p':
      default:
        note = 0;
    }

linea 170: quando il suono deve emettere la nota 1 assegni alla variabile current_pin il valore corrispondente al pin p2 in questo caso il pin 2;

linee 174,178,182,186,190,194: assegni alla stessa variabile current_pin il valore del pin corrispondente ad ogni nota;

    if(note) {
      Serial.print("Playing: ");
      Serial.print(scale, 10); Serial.print(' ');
      Serial.print(note, 10); Serial.print(" (");
      Serial.print(notes[(scale - 4) * 12 + note], 10);
      Serial.print(") ");
      Serial.println(duration, 10);
      tone1.play(notes[(scale - 4) * 12 + note]);
      digitalWrite(current_pin,HIGH);
      delay(duration);
      tone1.stop();
      digitalWrite(current_pin,LOW);
    } else {
      Serial.print("Pausing: ");
      Serial.println(duration, 10);
      delay(duration);
    }

linea 235: subito dopo aver inviato la nota allo speaker accendi il led, porta ad HIGH il valore del pin corrispondente al led da accendere;

linea 236: la nota e di conseguenza l’accensione del led è in pausa per il tempo definito di durata della nota;

linea 238: spegni i led acceso alla linea 235;

Il video con le suonerie e i led

Buona realizzazione !!!
