Code For the Piano

Arduino
Deploy this code on your arduino Leonardo or UNO
// Name the pin as led.
#define speaker 11

// Set the Snt end Pin & Receive Pin.
int trig = 12;
int echo = 13;
long cmm;

void setup()
{
pinMode(trig, OUTPUT);
digitalWrite(trig, LOW);
pinMode(echo, INPUT);
Serial.begin(9600);
}

void loop()
{
// Set a timer.
long start = millis();

cmm=What_Range();

if(cmm>10 && cmm<70)
{
tone(speaker, 440*cmm/30);
delay(100);
}
else
{
delay(10);
}

Serial.println(cmm);
noTone(speaker); // arbitrary delay to limit data to serial port
}

int What_Range()
{
int cm;
digitalWrite(trig, HIGH);
delayMicroseconds(10);
digitalWrite(trig, LOW);
