Uploading a new code:

1. Take the battery out.

2. Download the arduino programming application: https://www.arduino.cc/en/Main/Software

3. Download the required libraries. To do this, open the arduino application. 
Go to Sketch>Include Library>Manage Libraries. 
There will be a popup with a list of libraries you can install. 
The ones you need are called FastLED and IRremote.
