- For a DIATONE 3x4 WS2812 LED Matrix, which is often used in FPV drone builds, it's usually controlled through flight controller firmware like Betaflight or Cleanflight, as they have built-in support for WS2812 LEDs.
- However, if you want to control it using an Arduino or ESP32, you can use the Adafruit_NeoPixel library. The DIN (Data IN) pin is used to send data to the LED matrix.
- In this code, replace LED_PIN with the pin connected to the DIN of your LED matrix, and LED_COUNT with the total number of LEDs in the matrix. This code will light up each LED in a random color and refresh every half a second.
- Please note the Adafruit_NeoPixel library uses a considerable amount of dynamic memory, so be aware if your project has other memory requirements.
- Here's an example of how to light up the matrix in different colors:
- */
- #include <Adafruit_NeoPixel.h>
- #define LED_PIN 2 // The pin your LED strip is connected to
- #define LED_COUNT 12 // The number of LEDs in the matrix
- // Declare our NeoPixel strip object:
- Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);
- void setup() {
- strip.begin(); // Initialize the NeoPixel library
- strip.show(); // Initialize all pixels to 'off'
- }
- void loop() {
- // Make the LEDs show different colors
- for(int i=0; i<LED_COUNT; i++) {
- strip.setPixelColor(i, strip.Color(random(0,255), random(0,255), random(0,255))); // Random color
- }
- strip.show(); // Send the updated pixel colors to the hardware.
- delay(500); // Pause before next pass through loop
- }
