Using Puck as a single button keyboard

Just thought I'd share the finished code for sending a word with a click of the button as a BLE HID Keyboard, not yet tried linking to the RasPi but works great with my iMac

var kb = require("ble_hid_keyboard");
NRF.setServices(undefined, { hid : kb.report });
var reset_timer;
var char_timer;
var arr;

var word = "Hello";


function send(){
  LED3.set();
  arr = word.split("");
  char_timer = setInterval("sendChar()", 100);
  LED2.set();
  setTimeout("LED2.reset()",1000);
  LED3.reset();
}

function onTimeout() {
  setTimeout("LED1.reset()",5000);
  LED1.set();
  LED3.reset();
}

function sendChar(){
    if (arr.length !== 0){
        var char = arr.shift();
        if (char == char.toLowerCase())
        {
            sk = 0;
        }
        else
        {
            sk = 0x02;
        }
        kb.tap(kb.KEY[char.toUpperCase()], sk);
    }
    else{
        clearInterval(char_timer);
    }
}

setWatch(function() {
  send();
  }, BTN, {edge:"rising", debounce:50, repeat:true});
