o que eu fui entendendo.
mas não consigo de jeito nenhum fazer os efeitos da fita mudarem ao pressionar o botão.
eu gostaria de saber também como posso fazer um efeito pra fita interagir com o som ambiente ou através de uma entrada de som.
se alguém souber de outros efeitos legais que eu possa usar também será bem vindo.
segue o código:
// This is a demonstration on how to use an input device to trigger changes on your neo pixels.// You should wire a momentary push button to connect from ground to a digital IO pin. When you// press the button it will change to a new pixel animation. Note that you need to press the// button once to start the first animation!#include <Adafruit_NeoPixel.h>#define BUTTON_PIN 2 // Digital IO pin connected to the button. This will be // driven with a pull-up resistor so the switch should // pull the pin to ground momentarily. On a high -> low // transition the button press logic will execute.#define PIXEL_PIN 6 // Digital IO pin connected to the NeoPixels.#define PIXEL_COUNT 30// Parameter 1 = number of pixels in strip, neopixel stick has 8// Parameter 2 = pin number (most are valid)// Parameter 3 = pixel type flags, add together as needed:// NEO_RGB Pixels are wired for RGB bitstream// NEO_GRB Pixels are wired for GRB bitstream, correct for neopixel stick// NEO_KHZ400 400 KHz bitstream (e.g. FLORA pixels)// NEO_KHZ800 800 KHz bitstream (e.g. High Density LED strip), correct for neopixel stickAdafruit_NeoPixel strip = Adafruit_NeoPixel(PIXEL_COUNT, PIXEL_PIN, NEO_GRB + NEO_KHZ800);bool oldState = HIGH;int showType = 0;void setup() { pinMode(BUTTON_PIN, INPUT_PULLUP);
