LED - RGB Intensity
Demonstrates changing intensity of an RGB LED. Requires RGB LED on pins that support PWM (usually denoted by ~).
RGB LED. (Arduino UNO)
RGB LED connected to pins 6, 5, and 3 for red, green, and blue respectively.

Run this example from the command line with:
node eg/led-rgb-intensity.js
var temporal = require("temporal");
var five = require("johnny-five");
var board = new five.Board();
board.on("ready", function() {
// Initialize the RGB LED
var led = new five.Led.RGB([6, 5, 3]);
// Set to full intensity red
console.log("100% red");
led.color("#FF0000");
temporal.queue([{
// After 3 seconds, dim to 30% intensity
wait: 3000,
task: function() {
console.log("30% red");
led.intensity(30);
}
}, {
// 3 secs then turn blue, still 30% intensity
wait: 3000,
task: function() {
console.log("30% blue");
led.color("#0000FF");
}
}, {
// Another 3 seconds, go full intensity blue
wait: 3000,
task: function() {
console.log("100% blue");
led.intensity(100);
}
}, ]);
});
