Sketch: void setup { // initialize serial communications Serial.begin(9600); }

void loop { // read the sensor: int sensorReading = analogRead(A0); // print the sensor reading so you know its range Serial.println(sensorReading); // map the pitch to the range of the analog input. // change the minimum and maximum input numbers below // depending on the range your sensor's giving: int thisPitch = map(sensorReading, 400, 1000, 100, 1000);

// play the pitch: tone(9, thisPitch, 10);
