I'm still new to Arduino and electronics so if this doesn't make sense, excuse me.
I like just about everything Arduino has to offer, however, if I want to make a permanent solution, I don't want to have to use a Uno or a Pro to do it. I want to just be able to have an Atmel MCU on a board I designed.
What's the best way to do this? Right now I'm trying to do a digital voltmeter for a bench supply I'm making. I can make it on a standard Arduino, but when I want to finalize that, can I just extract the programed chip and put it in the circuit and hook up all of the pins accordingly? I don't need to be on an Arduino board in order to run Arduino sketches do I?
