I don't even know if this is appropriate here, but i know that this could have aquarium applications too, sooo.. i hope it flies. I'm trying to build a low-temperature alarm using a DS18B20 temperature sensor, a Leonardo Pro Mini with the ATmega32u4, and a 3W Cree LED... I first began with the set up described here:
but quickly realized that i didn't want to log the temperatures so much as have decision criteria
I have seen things like this:
and i imagine that i could use their code for most of what i want to do, but since A) i already bought the mini boards (evilbay # 171195874012) i was hoping to use them. and, i have no desire to have speakers, rather i would like to have the LED light up...
SO, I'm a little ashamed asking for help, as the majority of the threads here are of awesome people doing awesome things... but hey.. i need help! I'm currently mid-build on my iAqua, and i had the brilliant idea to start ANOTHER project..
I'll be honest, this isn't entirely an aquarium application.. I am a property manager, and i would love to be able to give tenants one of these to put in their house when they go on break, so that i can just drive by and see if anyone's pipes are about to freeze! essentially something like this..
eventually i would like to move this onto an UNO and add a wifi shield to be able to get email notifications of temperatures dropping below the threshold, and perhaps even integrate a touch screen, but for now, i would just settle for something to keep any more pipes from freezing!! Thanks for reading my sob story!! you guys on the DIY thread here are seriously the best.
