Another project again. This time it'll be about music. For each button I press, it will play a note on the piezo speaker. I've used:
 |
| Arduino Uno |
 |
| Piezo Speaker |
 |
| 1K Ohm Resistor |
 |
| Jumper Wires |
int serial_in;
void setup()
{
pinMode(8,OUTPUT); // pin 8 connected to the piezo speaker
Serial.begin(9600);
}
void loop()
{
if(Serial.available()){ // see if there is anything incoming
serial_in=Serial.read();
Serial.println(serial_in,BYTE); // print in the incoming bytes
}
switch(serial_in){
case '1':
tone(8,523); // DO
break;
case '2':
tone(8,587); // RE
break;
case '3':
tone(8,622); // MI
break;
case '4':
tone(8,698); // FA
break;
case '5':
tone(8,783); // SO
break;
case '7':
tone(8,830); // LA
break;
case '8':
tone(8,932); // TI
break;
case '9':
tone(8,1046); // DO
break;
case '0':
noTone(8); // no note played
break;
}
}
And here's how it works! Enjoy!
