13. Skin Electronics

Inspiration

For this project I wanted to make something which made a link with my final project, or something that can be used later on with my capsule collection, So I decided to make a headgear which is inpired from the cellular structures of our 3 best friends - Algae, Bacteria and Mycelium.

When Joseph, our lab instructor, showed us an example of acrylic 3D lamp, I got very inspired from that, as I always wanted to work with holograms and this was something like holograms.

Electronics

This week we learnt how to train ATtiny using arduino, so that we can use ATtiny and a battery for wearables or skin electronics.

Code used for the Neopixels

#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
#include <avr/power.h> // Required for 16 MHz Adafruit Trinket
#endif

// Which pin on the Arduino is connected to the NeoPixels?
// On a Trinket or Gemma we suggest changing this to 1:
#define LED_PIN    6

// How many NeoPixels are attached to the Arduino?
#define LED_COUNT 12

// Declare our NeoPixel strip object:
Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);


int sensor = A1;
int lecture = 0;

void setup() {
  // put your setup code here, to run once:
#if defined(__AVR_ATtiny85__) && (F_CPU == 16000000)
  clock_prescale_set(clock_div_1);
#endif
  // END of Trinket-specific code.

  strip.begin();           // INITIALIZE NeoPixel strip object (REQUIRED)
  strip.show();            // Turn OFF all pixels ASAP
  strip.setBrightness(50); // Set BRIGHTNESS to about 1/5 (max = 255)
  pinMode(sensor, INPUT);
  Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:
  lecture = analogRead(sensor);
  lecture = constrain(lecture, 220, 800);
  Serial.println(lecture);
  if (lecture < 400) {
    strip.fill(strip.Color(0,0,255), 0,12);
  }
  else if (lecture < 600) {
    strip.fill(strip.Color(255,0,55), 0,12);
  }
  else{
    strip.fill(strip.Color(255,255,255), 0,12);
  }
  strip.show();
  delay(100);

}

void colorWipe(uint32_t color, int wait) {
  for(int i=0; i<strip.numPixels(); i++) { // For each pixel in strip...
    strip.setPixelColor(i, color);         //  Set pixel's color (in RAM)
    strip.show();                          //  Update strip to match
    delay(wait);                           //  Pause for a moment
  }
}
