I just got some DS1621 I2C 5V PDIP-8 Temperature Sensors and with a quick google search I found some code from Jon McPhalen.
I added my LCD screen code and a Celsius to Fahrenheit float conversion and I had an easy Temperature Monitor built up in less than a 30mins. Fun lunch hour project! .... Now back to work :P
Click the link below to get to my modified code:
Now I have to clean up the code and combine the Real-Time-Clock and Temp Sensor into one build... but that is for another lunch hour;P
