CONTENUTO ►
Progetto su Arduino Uno – pianoforte con pulsanti e squeaker. Il progetto richiede un numero minimo di componenti, disponibili in qualsiasi starter kit. L’articolo presenta uno schema dell’assemblaggio del pianoforte su una breadboard e un programma funzionante per il microcontrollore Arduino. Per realizzare il circuito è possibile utilizzare, oltre alla scheda Uno, anche le schede Arduino Nano e Mega 2560; il programma rimarrà invariato.
Per questa attività sono necessari:
- Arduino Uno / Arduino Nano / Arduino Mega
- buzzer attivi o passivi
- pulsanti
- breadboard
- cavi di collegamento
Come costruire pianoforte Arduino con buzzer
Lo schema di montaggio può sembrare complicato a prima vista, ma non lo è affatto. I pulsanti dell’orologio sono posizionati al centro della breadboard, il pin GND è collegato al contatto inferiore del pulsante e il contatto superiore del pulsante è collegato al pin digitale del microcontrollore. Il cicalino è collegato con due contatti al pin GND (massa) e al pin 12. Anche nella variante presentata viene utilizzato il LED incorporato sul pin 13.

Spiegazione del codice per piano con buzzer e pulsanti:
- i pin per il collegamento dei pulsanti sono configurati in modalità INPUT_PULLUP all’interno del ciclo for();
- quando il pulsante viene premuto, il LED integrato deve accendersi.
Conclusione. Il buzzer attivi è controllato dal microcontrollore Arduino mediante i comandi tone e noTone. Nel progetto possono essere utilizzati sia cicalini attivi che passivi. Nella funzione void midi() è presente una melodia dimostrativa sul pianoforte, al posto della quale è possibile inserire la propria melodia. Ci auguriamo che il nostro progetto sia interessante e utile per voi nel processo di apprendimento del linguaggio Arduino.
