LEDs - An array of LEDs

Demonstrates controlling multiple LEDs at once through the use of an LED array. Requires LEDs on pins that support PWM (usually denoted by ~).

Run this example from the command line with:

node eg/led-array.js

const {Board, Leds} = require("johnny-five");
const board = new Board();

board.on("ready", () => {
  const leds = new Leds([3, 5, 6]);

  leds.pulse();
});

Additional Notes

Control multiple LEDs at once by creating an LED collection (Leds). All must be on PWM pins if you want to use methods such as pulse() or fade()
