title: Using LCD Library with Johnny Five on Node Js and Arduino
body: <p>I am trying to make my lcd turn it off the backlight and on again.</p>
  
  <p>The command to turn it on: <code>lcd.noBacklight();</code> is working fine, but I don't know how to turn it on again.</p>
  
  <pre><code>var five = require("johnny-five");
  var board = new five.Board();
  
  board.on("ready", function() {
  
    var lcd = new five.LCD({
      controller: "PCF8574T"
    });
  
    lcd.cursor(0, 0).print("1 Hello Teste");
    lcd.cursor(1, 0).print("2 Hello Teste");
    lcd.cursor(2, 0).print("3 Hello Teste");
    lcd.cursor(3, 0).print("4 Hello Teste");
  
    lcd.noBacklight();
  
    setTimeout(() =&gt; {
      lcd.yesBacklight(); //Here I don't know what to do
    }, 1500);
  
    setInterval(() =&gt; {
      lcd.noBacklight();
    }, 1500);
  
  
  });
  </code></pre>
  
  <p>How could I turn it on again?</p>
