Description

Create a single artifact that incorporates both input and output. I made a musical squeeze box using a cardboard box. When you squeeze the sides of the box it outputs a musical tone. You can twist the knob at the end to change the pitch of the output noise (musical note).

Components Used

1 Resistors

1 Potentiometers 

1 Force Sensitive Resistor

1 Piezo Speaker

cardboard box and sponge foam 

Arduino Code

/*
 * Joshua Gomez - Lab 5
 *
 * This code is for a music box
 * By pressing the button a sound is emitted
 * The sound played is detremined by the value of the POT input
 */

int potPin = 0;    // select the input pin for the potentiometer
int fsrPin = 5;    // select the input pin for the FSR
int speakerPin = 11;// set the output pin for the piezo speaker

int potVal = 0;
int fsrVal = 0;

void setup() {
  pinMode(speakerPin, OUTPUT);
  beginSerial(9600);
  Serial.println("ready");
}

void loop() {
  fsrVal = analogRead(fsrPin);
  if(fsrVal>10)
  {
    potVal = analogRead(potPin) + 950;
    for( int i=0; i<200; i++)
    {
      digitalWrite(speakerPin, HIGH);
      delayMicroseconds(potVal);
      digitalWrite(speakerPin, LOW);
      delayMicroseconds(potVal);
    }
  }
  else
    digitalWrite(speakerPin, LOW);
}
