RGB test

Functionality

The RGB light on the ReSpeaker Lite board is using the WS2812 chip and controlled via the GPIO1 pin. The project cycles through different colors (red, green, blue, and white) to ensure that the RGB light is functioning properly.

Code

#include <Adafruit_NeoPixel.h>

// Define parameters for the LED strip
#define PIN 1            // Pin connected to the RGB LED
#define NUMPIXELS 1      // Number of LEDs

Adafruit_NeoPixel strip(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);  // Initialize the LED strip object

void setup() {
  // Initialize the serial monitor for debugging
  Serial.begin(115200);
  
  // Initialize the RGB LED strip
  strip.begin();
  strip.show();  // Initialize all pixels to the off state
}

void loop() {
  // Red color test
  Serial.println("Red color test");
  strip.setPixelColor(0, strip.Color(255, 0, 0));  // Set the first pixel to red
  strip.show();  // Update the strip display
  delay(1000);   // Delay for 1 second

  // Green color test
  Serial.println("Green color test");
  strip.setPixelColor(0, strip.Color(0, 255, 0));  // Set the first pixel to green
  strip.show();
  delay(1000);

  // Blue color test
  Serial.println("Blue color test");
  strip.setPixelColor(0, strip.Color(0, 0, 255));  // Set the first pixel to blue
  strip.show();
  delay(1000);

  // White color test
  Serial.println("White color test");
  strip.setPixelColor(0, strip.Color(255, 255, 255));  // Set the first pixel to white
  strip.show();
  delay(1000);

  // Turn off the LED
  Serial.println("Turn off the LED");
  strip.setPixelColor(0, strip.Color(0, 0, 0));  // Turn off the first pixel
  strip.show();
  delay(1000);
}

Configuration

strip.setPixelColor: set the color LED in the strip.

strip.show: applies the color changes to the LED.
