Living Architecture Fall 2009 Pratt

Description:
We have taken our portable Prototype #6 and adapted it to become 'wearable'.
We switch our input back to the piezo element due to its robustness and ease of adaptability for the shoe.

Input:
Tapping of the shoe

Output:
LED turns ON and OFF

Setup:





















Result:


Code:
/* Knock Sensor
* ----------------
*
* Program using a Piezo element as if it was a knock sensor.
*
* We have to basically listen to an analog pin and detect
* if the signal goes over a certain threshold. If the Threshold
* is crossed, and toggles the LED on pin 13.
*
* Modified from one by (cleft) 2005 D. Cuartielles for K3

int ledPin = 13;
int knockSensor = 2;
byte val = 0;
int statePin = LOW;
int THRESHOLD = 1; // if it's too sensitive then change this value

void setup()
{
pinMode(ledPin, OUTPUT);
}

void loop()
{

if (val >= THRESHOLD) { // check the piezo
statePin = !statePin; // sets the pin to the opposite state
digitalWrite(ledPin, statePin); // turn on or off the LED
}
