Sul sul!
For Halloween this year we dressed up as the Pleasant sisters, Lilith and Angela Pleasant, from the Sims including a Plumbob with lights to display all of the different Sims’ emotions.
I, Ana, grew up playing Sims (maybe too early in my life) and I’ve always wanted to be a Sim for Halloween. When we were brainstorming ideas for Halloween, I shared with Sophia that I was thinking of being a Sim, and she loved the idea. On that day… Sophia and I became Sims, the Pleasant sisters to be exact. Overall, it was really fun to get dressed up and be a Sim for a little bit but I do think we can make some improvements. It felt pretty uncomfortable and not too secure to be wearing a wig and a headband and a tall wire on our heads, so I think for next time, maybe we would make the height of the Plumbob a little shorter so the weight distribution doesn’t have as much effect. Also maybe we would professionally hire someone to put the wigs on us 😅
and I, Sophia, approve this message hehe
Materials and parts used:
- Blank Mylar Stencil Sheets
- Headband
- Red wig
- 20 gauge wire from VFL
- Cute outfit <3
- Gemma M0
- 2x NeoPixel LED Strips
- Plumbob template below
After much trial and tribulation here is our Arduino code that triggers the 5 different Sims color emotions with the push of a button on our headbands
// Simple demonstration on using an input device to trigger changes on your
// NeoPixels. Wire a momentary push button to connect from ground to a
// digital IO pin. When the button is pressed it will change to a new pixel
// animation. Initial state has all pixels off -- press the button once to
// start the first animation. As written, the button does not interrupt an
// animation in-progress, it works only when idle.
#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
#include <avr/power.h> // Required for 16 MHz Adafruit Trinket
#endif
// Digital IO pin connected to the button. This will be driven with a
// pull-up resistor so the switch pulls the pin to ground momentarily.
// On a high -> low transition the button press logic will execute.
#define BUTTON_PIN 2
#define PIXEL_PIN 1 // Digital IO pin connected to the NeoPixels.
#define PIXEL_COUNT 8 // Number of NeoPixels
// Declare our NeoPixel strip object:
Adafruit_NeoPixel strip(PIXEL_COUNT, PIXEL_PIN, NEO_GRBW + NEO_KHZ800);
// Argument 1 = Number of pixels in NeoPixel strip
// Argument 2 = Arduino pin number (most are valid)
// Argument 3 = Pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
// NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products)
