It took a little prodding to learn how to store a color value and that the color should only change when the hexagon is newly pressed. The basic gist of it is: brighten the matching pendant pixel (i.e., front left hexagon pressed, bottom left pixel lights up) and change the color of all pixels. This was an enjoyable bit of code to arrive at. This proved to be one of the most helpful techniques I took from this build.Īfter adding the snaps I flashed a quick test script to use for the majority of the build: #ifdef _AVR_ #include // Required for 16 MHz Adafruit Trinket #endif #include #define THRESHOLD 200 int ledPin = 7 long total CapPin capPin = CapPin(0) void setup() I soldered snaps onto my Flora circuit board for easy testing and removal. Luckily, right before beginning to glue, I found the Plush Game Controller tutorial, which features a route for detecting changes in capacitance without a round trip and without a resistor! The complexity of the skirt was cut in half.

Originally I was taking inspiration from Capacitive Touch with Conductive Fabric & Flora and had a resistor for each conductive hexagon.

Before gluing or soldering anything, I prototyped with a bunch of banana clips.
