Mini Project 2: Impact

Impact --||

My second mini project, a metaphor for human impact on an environment and how intervening in one area can can cause a chain reaction throughout an ecosystem. This project is composed of hand-crocheted flowers laced with conductive thread, a plush fabric landscape, and a lilypad arduino. When the first flower is touched, it 'dies', the light in it's center going out and causing a chain reaction throughout the other flowers.

Video of the project in action:

Code (Under Read More):


#define COMMON_PIN      5    // The 'send' pin for all flowers
#define NUM_OF_SAMPLES  30   // Higher number whens more delay but more consistent readings
#define CAP_THRESHOLD   100  // Capactive reading that triggers the light
#define NUM_OF_S     1    // Number of flower sensors
#include <CapacitiveSensor.h>
#include "pitches.h"

// Defines the pins that the flowers are connected to:
CapacitiveSensor   cs_4_2 = CapacitiveSensor(5,7);
int mode = 0;

void setup() {
  cs_4_2.set_CS_AutocaL_Millis(0xFFFFFFFF);
 
    pinMode(6, OUTPUT);
    pinMode(8, OUTPUT);
    pinMode(10, OUTPUT);
    pinMode(12, OUTPUT);
    //flowers are on in the beginning
  digitalWrite(6, HIGH);
  digitalWrite(8, HIGH);
  digitalWrite(10, HIGH);
  digitalWrite(12, HIGH);

}

void loop() {   
 
   long total1 =  cs_4_2.capacitiveSensor(30);
    // If the capacitance reading is greater than the threshold, play a note:
    if(cs_4_2.capacitiveSensor(30) > CAP_THRESHOLD) {
 digitalWrite(6, LOW); // Turns off the corresponding light
      mode = 1;
    }
    else if(mode == 1)
   {
     delay(100);
     digitalWrite(6, LOW); //Keeps light off
    delay(500);
    digitalWrite(8, LOW);
        delay(500);
    digitalWrite(10, LOW);
        delay(500);
    digitalWrite(12, LOW);
   }
  
    else{
       digitalWrite(6, HIGH); //Otherwise it's on.
       
    }
