Demonstrates use of an RGB LED (common cathode) by setting its color to red (#ff0000) and making it blink. Requires RGB LED on pins that support PWM (usually denoted by ~).

Common Cathode RGB LED. (Arduino UNO)

RGB LED connected to pins 6, 5, and 3 for red, green, and blue respectively. The common pin is connected to ground.

Run this example from the command line with:

node eg/led-rgb.js
var five = require("johnny-five");

five.Board().on("ready", function() {

  // Initialize the RGB LED
  var led = new five.Led.RGB({
    pins: {
      red: 6,
      green: 5,
      blue: 3

  // RGB LED alternate constructor
  // This will normalize an array of pins in [r, g, b]
  // order to an object (like above) that's shaped like:
  // {
  //   red: r,
  //   green: g,
  //   blue: b
  // }
  //var led = new five.Led.RGB([3,5,6]);

  // Add led to REPL (optional)
    led: led

  // Turn it on and set the initial color
