About this 3D model

Led is sound reactive heres the code: Also a youtube video demonstrating it. I will create the mask if enough people have interest but heres something Tali cosplayers can use for their masks. Code: include include ifdef AVR include endif define PIN 6 define NUMPIXELS 1 //==============Defining variables for fix_fft======================= int x = 0; char im[128], data[128]; char data_avgs[14]; int i = 0, val, steady; int l = 0; Adafruit_NeoPixel pixel = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800); void setup() { Serial.begin(9600); pixel.begin(); pixel.show(); } void loop() { //===================FFT algorithm======================= for (i = 0; i < 128; i++) { val = analogRead(A9); steady = val; data[i] = val; im[i] = 0; } fix_fft(data, im, 7, 0); for (i = 0; i < 64; i++) { data[i] = sqrt(data[i] data[i] + im[i] im[i]); } for (i = 0; i < 14; i++) { data_avgs[i] = data[i 4] + data[i 4 + 1] + data[i 4 + 2] + data[i 4 + 3]; data_avgs[i] = map(data_avgs[i], 0, 30, 0, 9); } int value = data_avgs[0]; Serial.print("Time domain: "); Serial.println(steady); Serial.print("Frequency domain: "); Serial.println(value); delay(100); pixel.setPixelColor(0, 75, 0, 130); //change color here by changing RGB values. In this case R=150, G=150, B=150 int bValue = map(value, 0, 30, 0, 255); pixel.setBrightness(bValue); pixel.show(); }
