Max is still kickin it, he writes – “Okay you’ve built the digital thermometer but you ran out of ideas and didn’t know what to do with it. Well if you wanted to, you could add a Lantronix XPORT ethernet serial device to the serial channel and monitor temperature remotely over the ethernet. Now I have the ability to check temperature of my room even when i am in Hawaii or New York! The greatest thing about these little XPORTs is that you can enable any microcontroller w/ serial ports to be ethernet ready.”Link.
