Financial Report (password required)

We have a pond in the back yard that is home to a number of fish.  They love to eat and look forward to my visits.  Unfortunately it is not healthy for the fish to be fed when the temperature of the pond water is 50 degrees Fahrenheit or lower. 

To keep track of this I built up a wireless temperature reporting system using a pair of Arduinos, wireless transmitter/receiver modules, an LCD display and a temperature sensor.
