Sensor de Temperatura

LM35

var five = require("johnny-five");

five.Board().on("ready", function() {
  var temperature = new five.Temperature({
    controller: "LM35",
    pin: "A0"
  });

  temperature.on("data", function() {
    console.log(this.celsius + "°C", this.fahrenheit + "°F");
  });
});

Motor

var five = require("johnny-five"),
  board, motor, led;

board = new five.Board();

board.on("ready", function() {
  // creamos una nueva instancia "motor" en nuestro hardware,
 //el cual funcionara por el pin 5
  motor = new five.Motor({
    pin: 5
  });

 //agregamos el nuevo hardware a nuestra arduino
  board.repl.inject({
    motor: motor
  });

 //api de eventos del motor

  // eventos cuando el motor ese encendido
  motor.on("start", function() {
    console.log("start");

    // el motor girara 5 segundos
    board.wait(5000, function() {
      motor.stop();
    });
  });

 

 // metodo para detener el motor
  motor.on("stop", function() {
    console.log("stop");
  });

  
  motor.start(); // inicia el motor

   stop()
  
});
