The JavaScript Arduino Programming Framework.

var five = require("../lib/johnny-five.js"),
  board = new five.Board();

board.on("ready", function() {
  // Default to pin 13
  var led = new five.Led(process.argv[2] || 13);

  this.repl.inject({
    led: led
  });

  led.blink();
});

// This script will make `led` available in the REPL, by default on pin 13.
// Now you can try, e.g.:
//
// `>> led.on()`
//
// or
//
// `>> led.off()`
//
// To use other `Led` methods, like `fade`, `pulse`, `animate`, you'll need to
// wire the LED to a PWM pin. If you use a different pin, make sure to run
// the script with the correct pin number:
//
// `node eg/led.js [pinNumber]`
