Play with RGB LEDs [Code]

Changer la couleur de la LED entre le rouge, le vert et le bleu
LED user allumé
LED RGB change de couleur, mais lumiere très forte

Bibliothèque : https://github.com/adafruit/Adafruit_NeoPixel

#include <Adafruit_NeoPixel.h>

#define LED_PIN RGB_BUILTIN  // Define the pin for the built-in RGB LED
#define NUM_PIXELS 1         // Number of WS2812 LEDs

Adafruit_NeoPixel pixels(NUM_PIXELS, LED_PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  pinMode(PIN_RGB_EN, OUTPUT); // Set up the power pin
  digitalWrite(PIN_RGB_EN, HIGH); //Turn on power to the LED
  pixels.begin();  // Initialize the NeoPixel library
}

void loop() {
    // Transition from Red to Green
  for (int i = 0; i <= 255; i++) {
    pixels.setPixelColor(0, pixels.Color(255 - i, i, 0));  // Red decreases, Green increases
    pixels.show();
    delay(10);  // Adjust delay for smoothness
  }

  // Transition from Green to Blue
  for (int i = 0; i <= 255; i++) {
    pixels.setPixelColor(0, pixels.Color(0, 255 - i, i));  // Green decreases, Blue increases
    pixels.show();
    delay(10);  // Adjust delay for smoothness
  }

  // Transition from Blue to Red
  for (int i = 0; i <= 255; i++) {
    pixels.setPixelColor(0, pixels.Color(i, 0, 255 - i));  // Blue decreases, Red increases
    pixels.show();

Adjust delay for smoothness : Ajustez le délai pour plus de fluidité

Hello Word ! [Code] & OLED Display 1.12

Grove Base for XIAO
XIAO-RA4M1
OLED Display 1.12 (v2.1) 128 × 128 pixels, Port I2c

int y_offset = 16; // Valeur typique pour SH1107
u8g2.drawStr(0, 24 + y_offset, "Hello World!");
à Tester

bug classique** avec les écrans OLED SH1107 et la bibliothèque **u8g2** : la commande `drawStr(x, y, ...)` ne positionne pas le texte comme prévu.
