Introduction: Arduino Tutorial 7: Super Mario Bros Theme With Buzzer
Il buzzer è un dispositivo che emette semitoni con una qualità grezza, sotto forma di onda quadra,è impiegato tutt'ora nei pc per indicare gli errori del sistema o del bootloader.
The buzzer is a semitone device with crude quality,in the form of square wave, it is still used on PCs to indicate system or bootloader errors.
Step 1: Progettazione / Design
Il collegamento del buzzer ad Arduino è molto semplice:
Un terminale (quello nero) va a GND, mentre l'altro (quello rosso) va ad un pin di Arduino a scelta (nel mio caso è il 10) .
Materiale Occorrente:
- Buzzer.
The connection of the buzzer to Arduino is very simple:
A terminal (the black one) goes to GND, while the other (the red one) goes to an Arduino pin of choice (in my case it's 10).
Material Required:
- Buzzer.
Step 2: Programmazione/Programming
In questo programma vengono usate solo due funzioni specifiche:
- "tone(nomebuzzer,freq);" dopo aver inserito il nume del pin del buzzer, definiamo la frequenza del suono emesso;
- "notone(nomebuzzer);" viene fermata la generazione di frequenze sonore, non viene più emesso alcun suono.
Il programma quindi genererà una frequenza sonora di 1000Hz per 1 secondo, ci sarà un'altro secondo di latenza senza alcun suono e poi si ripeterà questo ciclo.
Only two specific functions are used in this program:
- "tone (namebuzzer, freq);" after inserting the pin number of the buzzer, we define the frequency of the sound emitted;
- "notone (namebuzzer);" the generation of sound frequencies is stopped, no sound is output anymore.
The program then generates a 1000Hz sound frequency for 1 second, there will be another second of latency without any sound and then repeat this cycle.
#define buzzer 10 //Il buzzer è connesso al pin 10
void setup()
{
pinMode(buzzer,OUTPUT);
}void loop()
{
tone(buzzer,1000); //Si sente un tono sul pin 10 con una frequenza di 1000Hz
delay(1000); //aspetta 1 secondo
noTone(buzzer); //non suona
delay(1000); //aspetta 1 secondo
}Step 3: Super Mario Bros Theme
Attraverso una forma più sofisticata di programma, andremo a generare la sigla di Super Mario Bros, assegnando ad ogni Nota una frequenza diversa.
Il pin di Arduino per il buzzer è il 10.
ATTENZIONE: Questo non è un programma scritto da me, bensì da un'altro utente.
Through a more sophisticated form of program, we will create the Super Mario Bros Theme, assigning each note a different frequency.
The Arduino's pin of buzzer is 10.
ATTENTION: This is not a program written by me, but by another user.
