Process nearly complete (Mwah-ha-ha)

I've got the pipe fabricated, I've got the Piezo Vibration Sensor working, I've got the Arduino Mega working, now I just need to solder 100 LEDs and build the display, no big deal! I've been keeping process work of my ideation here: https://medialab.arts.ufl.edu/groups/art4642cfabrication/wiki/27e0b/Emily_Sneeden.html

I've changed my material from plexiglass to cardboard because I was inspired by: Scott Roberts

and I really like Joseph De Lappe's cardboard head.

Some imagery of the eyes I plan to inkjet print on to sticker paper, laser cut, and attach to the cardboard sculpture are:

Here's a video of how my test of the sensor to LED connection went!

Not sure how to attach the .pde so here's my code so far

const int knockSensor = A0; // the piezo is connected to analog pin 0

const int threshold = 100; // threshold value to decide when the detected sound is a knock or not

// these variables will change:

int sensorReading = 0; // variable to store the value read from the sensor pin

byte ledPin1 = 4;

byte ledPin2 = 5;

byte ledPin3 = 6;

byte ledPin4 = 7;

void setup(){

pinMode(ledPin1, OUTPUT);

pinMode(ledPin2, OUTPUT);

pinMode(ledPin3, OUTPUT);

pinMode(ledPin4, OUTPUT);

Serial.begin(9600);

}

void loop() {

sensorReading = analogRead(knockSensor);

if (sensorReading >= threshold) {

digitalWrite(ledPin1, HIGH);

digitalWrite(ledPin2, LOW);

digitalWrite(ledPin3, LOW);

digitalWrite(ledPin4, HIGH);

digitalWrite(ledPin1, HIGH);
