Arduino Based Controller
Bob,
I too have been busy on other projects (those pesky home improvement things) but aquired an Arduino and have been playing it. As you had stated previously, the Log function does allow me to calculate the dew point.
Curious about which temperature sensors you are using - the Dallas 1 wires or discrete? Are you measuring the relative humidity and again which sensor?
I had decided to use an LCD only for prove-in and not integrate it into the final project. I will integrate a ISP/communication port so I can monitor the project with the laptop. The final board will have the ATmega328 (with or without bootloader) implemented directly. May even be the possibility of a Astronomy Dew Heater Shield in the future!
