Whishlist:

1. At Startup Email Raspberry Pi IP Address to Gmail √
	---- Repo Code: startup_mailer.py



2. Get Raspberry Pi to play audio via speakers
	Info: http://www.raspberrypi-spy.co.uk/2012/06/raspberry-pi-speakers-analog-sound-test/
	"sudo amixer cset numid=3 <n>"
	0 = auto,
	1 = analog,
	2 = hdmi
	Force Raspberry Pi to play sound via Speakers via command line
	"sudo amixer cset numid=3 1"



3. Play Video on smooth loop

4. Blink an LED when Video is playing √
	---- Repo Code: blinkLED.py



3. Shutdown RPI properly at the press of a button

 CODE_DRAFT. 

	# This script aims to play video on loop
	# While on loop - play the audio through the speakers
	# If the video is playing then blink LED
	# If the video is not playing then dont blink the LED
	# Get the RPI to wait for a button to be pressed and then properly shutdown
	# The button is to be connected on header 5 between pins 6 and 8.
