I’m building a barbecue temperature controller system using a pair of JeeNodes (atmega328p/Arduino compatible). I’m not much of an electronics engineer so I wanted to get other opinions on the circuit I’v scraped together from other/similar projects. I’ve attached my schematic.
My main concern is the voltage regulator, does the regulator and the caps connected to it appear sufficient?
My project needs to run a 12 volt blower, is tapping directly into the wall wart power, as I’ve drawn, okay?
While I understand the logic of the voltage regulator circuit I don’t know the math behind the cap selection, I’ve just used what I’ve seen elsewhere.
Are there any concerns here I should be aware of? Any precautionary/protection measures I should take?
All input is welcomed and greatly appreciated.
