How to send changes to a lever in Minecraft to a MQTT broker - and listen for changes in an Arduino

	var mqtt = require('sc-mqtt');
	var client = mqtt.client(); // local host is default. Otherwise use host, user/pwd
	client.connect();

	//Subscribe to changes in the state of the Arduino
	client.subscribe('/arduino/1/status');
	var player; // To remember who pulled the switch

	// Here we tell Minecraft to give us control after certain events
	events.on('player.PlayerInteractEvent', function (listener, event) {

ScriptCraft skript som skriver til en fil hver gang en spak blir trukket i

	//Her gir vi beskjed om å kalle en funksjon når visse hendelser skjer i Minecraft

	events.on('player.PlayerInteractEvent', function (listener, event) {
	// Vi må finne ut om det var en "Lever" (altså en spak) som ble trukket i. Nå gjelder det ALLE spaker :-)
	// Du kan hente ut spakens posisjon vha. block.location om du vil se etter en spesiell

	var type = block.getType();
	if(type==org.bukkit.Material.LEVER) {
