Jin’s halloween process—evil ratatouille

Why I made it:My Halloween costume named evil ratatouille, which is a character from the movie ratatouille named Colette Tatou（I’m sure you’ve all seen the movie before!） The reason for cos this character is because I really like the philosophy of this movie-everyone can cook.what is a coincidence that Zai and I came up with this idea at the same time(Her haircut is just like the Linguini, and mine is like Colette), so we decided to Cos them together.

How to Hold it: Two parts of my costume: Ratatouille and the chef jacket. You can just put on a chef’s outfit and hold a Ratatouille in your hand.(which is very easy to put on them)

Making process step:

1 test the Arduino code

2 Copy the code to the gemma board

3 repaint the chef outfit: use the red paint paint my palm, and paint some palms and blood stains on my clothes.(forgot record the process)

Adafruit_NeoPixel strip(PIXEL_COUNT, PIXEL_PIN, NEO_GRB + NEO_KHZ800);

boolean oldState = HIGH;

int mode = 0; // Currently-active animation mode, 0-9

void setup() {

pinMode(BUTTON_PIN, INPUT_PULLUP);

strip.begin(); // Initialize NeoPixel strip object (REQUIRED)

strip.show(); // Initialize all pixels to ‘off’

}

void loop() {

boolean newState = digitalRead(BUTTON_PIN);

if((newState == LOW) && (oldState == HIGH)) {

delay(20);

newState = digitalRead(BUTTON_PIN);

if(newState == LOW) { // Yes, still low

if(++mode > 8) mode = 0; // Advance to next mode, wrap around after #8

switch(mode) { case 0:

colorWipe(strip.Color( 0, 0, 0), 50); // Black/off

break;

case 1:

colorWipe(strip.Color(255, 0, 0), 50); // Red

Circuit diagram：

what you would do differently if you had to do it over again:
1 Replace the felt fabric with acrylic. （Preform better on Translucency ）
2 Use wood or corrugated board to make the pan so I can dig a slot in the bottom of the pan and hide the buttons underneath!
3 Use stronger battery
