Digital_RGB_LED_SKU__FIT0401-DFRobot

Introduction

This is a kind of chip_inside LED, so you can control each LED individually! It will be great wonderful when you change the color. And for the control of the LEDs, it only need one digital pin of your Arduino whose MCU power supplies from 3.3V-5V. It is using single thread zero yards communication protocol,"DIN" will receive the contrtol signal and transmit to the next LED via "DOUT" port. So these LED could be cascade connection, and individual control. It is amazing if you want to show some beatuy with LEDs.

void setup(){
 #include <Adafruit_NeoPixel.h>

#define PIN 6

// Parameter 1 = number of pixels in strip
// 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
//   NEO_KHZ400  400 KHz bitstream (e.g. FLORA pixels)
//   NEO_KHZ800  800 KHz bitstream (e.g. High Density LED strip)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(60, PIN, NEO_GRB + NEO_KHZ800);
