This color changing wearable will always be in harmony with the outfit it is pinned to. This brooch reads the color of a garment and turns either the complementary color or displays the missing two colors in the triadic color scheme. This project uses the Adafruit color sensor, Neopixels and an Arduino Mini 05.
Don’t remember color theory from art school?
Complementary colors are opposite each other on the color wheel, when paired they make a vibrant combination.
Triadic colors are 3 that are evenly spaced from each other on the wheel. When all are used together, it is recommended to let one be dominant and the other two be used as accents. The dominant is automatically the main color you are wearing, while the two lit panels act as your accent. The brooch has it covered!
Since the brooch is colored using light, the wheel to be referenced is the RGB color wheel.
WS2812B 5050 RGB LED with Integrated Driver Chip – 10 Pack: Make your own smart LED arrangement with the same integrated LED that is used in our NeoPixel strip and pixels. This tiny 5050 (5mm x 5mm) RGB LED is fairly easy to solder and is the most compact way possible to integrate multiple bright LEDs to a design. The driver chip is inside the LED and has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making your design minimal. Power the whole thing with 5VDC and you’re ready to rock. Read more.
Flora Color Sensor with White Illumination LED – TCS34725: Your electronics can now see in dazzling color with this lovely color light sensor. We found the best color sensor on the market, the TCS34725, which has RGB and Clear light sensing elements. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The filter means you’ll get much truer color than most sensors, since humans don’t see IR. The sensor also has an incredible 3,800,000:1 dynamic range with adjustable integration time and gain so it is suited for use behind darkened glass or fabric. Read more.
