# Name: Temp1
# Purpose: Sensing Temperature in Celcius
#
# Editor: Ali Mulla
# Version: 0.2 (untested)
# Created: 12/10/2013
# Copyright: No Copyright
# Thanks: This has been edited to display just the temp in celcius from
# from the brilliant example written by Simon Monk, Adafruit.
# This should work out of the box without having to edit the config file
# as is required in some guides.
