Fantastic job! Congratulations!One proposal, and it will be a perfect system. DS18B20 sensors can be connected on a single cable. It is more convenient. But then you need to know their address. Here is a sample of how addresses are assigned sensors: http://www.homebrewtalk.com/f51/arduino-networked-temperature-monitor-340294/index2.html#post4286666 The combination of both programs get a great system.My English is very bad, but I hope you got the idea...
i am also wondering if it is something with the ethernet shield. i have been able to crash the arduino if i purposfully send lots of information over to it really fast. it just stops responding.
i am also wondering why my arduino freezes when i have the watchdog enabled. should that not reset the system?
i tried to use the "Wstring.cpp" and "Wstring.h" from Paul Stoffregen's teensey system. everything compiled, but it would no longer function and i have not determined what is causing it to not work.
Go to the playground and look at the Time and TimeAlarms library. You don't have to actually set the time, but you already have an RTC, so it should be easy to do. In the Time header file are a lot of macros including days between dates and such. Also, out on the web are a ton of days between dates routines that you can use. Most of the samples also have the seconds between date that will work for you as well, although saving the unix time when you start and just subtracting it from the current time will give you seconds pretty easily.
Hi,No humidity sensor attached so far, just checking if all relays can be controlled in manual mode but for unknown reason humidifier does not turn off in manual mode.Any ideas ?thanks!
ps. Talking about RTC, which pin SCL and SDA is connected on the arduino board please ?
