LED on pin 13 (Arduino UNO)

LED inserted directly into pin 13


Fritzing diagram: led-13.fzz


Run this example from the command line with:

node eg/repl.js
var five = require("johnny-five");
var board = new five.Board();

board.on("ready", function() {
  console.log("Ready event. Repl instance auto-initialized!");

  var led = new five.Led(13);

    // Allow limited on/off control access to the
    // Led instance from the REPL.
    on: function() {
    off: function() {

Additional Notes

This script will make on() and off() functions available in the REPL:

>> on()  // will turn on the LED
>> off() // will turn off the LED
