bonjour
Jai un petit problème. Jai réussi a faire mon code pour faire allumer ma bande led ws2811 avec 4 bouton de chacune des couleur que je voulais mais le problème est lors du montage quand je branche mais bande led a mais bornier les boutons ne fonctionne pu et Jai juste la couleur blanche qui marche et plus aucun bouton marche après cela voici mon code et le schémas si quelqu'un peux Maider a comprendre le pourquoi
merci
#include <Adafruit_NeoPixel.h>
#define PIN 4
#define HIGH 1
#define LOW 0
// Parameter 1 = number of pixels in strip
// Parameter 2 = Arduino pin number (most are valid)
// Parameter 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)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(150, PIN, NEO_GRB + NEO_KHZ800);
// IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across
// pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input
// and minimize distance between Arduino and first pixel. Avoid connecting
// on a live circuit...if you must, connect GND first.
// constants won't change. They're used here to
// set pin numbers:
const int offPin = 10; // the number of the pushbutton pin
const int whitePin = 13;
const int greenPin = 6;
const int redPin = 8;
const int bluePin = 5;
// variables will change:
int offState = 0; // variable for reading the pushbutton status
int whiteState = 0;
int greenState = 0;
int redState = 0;
int blueState = 0;
int pixelSpeed = 10;

strip.begin();
strip.show(); // Initialize all pixels to 'off'
pinMode(offPin, INPUT_PULLUP);
pinMode(whitePin, INPUT_PULLUP);
pinMode(greenPin, INPUT_PULLUP);
pinMode(bluePin, INPUT_PULLUP);
pinMode(redPin, INPUT_PULLUP);
pinMode(13, OUTPUT);
}
void loop() {
// Some example procedures showing how to display to the pixels:
whiteState = digitalRead(whitePin);
offState = digitalRead(offPin);
greenState = digitalRead (greenPin);
blueState = digitalRead (bluePin);
redState = digitalRead (redPin);
if (greenState == LOW | redState == LOW | blueState == LOW) {
colorWipe(strip.Color(255 * (1-redState), 255 * (1-greenState), 255 * (1-blueState)), pixelSpeed); // RGB
}
else if (whiteState == LOW) {
colorWipe(strip.Color(255, 255, 255), pixelSpeed); // WHITE
}
else if (offState == LOW) {
colorWipe(strip.Color(0, 0, 0), pixelSpeed); // WHITE
}
}
// Fill the dots one after the other with a color
void colorWipe(uint32_t c, uint8_t wait) {
for(uint16_t i=0; i<strip.numPixels(); i++) {
strip.setPixelColor(i, c);
strip.show();
