/*
 This program read temperature using two LM35 
 sensors on A0 and A1 analog inputs and displays 
 average temperature using serial
 Also, if the temp is in the range (18,22) C then 
 the green led is on, if the temp is in the range 
 (16,18) and (22,24) C the blue led is on, else 
 red led will be on.
 You can see the connection diagram on my blog
 sdizdarevic.com soon
