You should give it a try IMHO.
SchemeIt is a free on line tool that makes very clear, professional diagrams.I agree with MorganS, don't use Fritzing. It is only for complete beginners, and is really terrible for anything more than the very simplest of circuits.
New to arduino, and to electronics. I see people posting nice diagrams with arduinos, breadboards, circuits...etc. what program/software are they using?I'm on a Mac if that matters.
