This question already has an answer here:
I just watched this excellent video tutorial that shows a simple Arduino program that toggles an LED via a pushbutton. Very cool!
In the video, the author is using a breadboard for prototyping his circuit. What's the next "step up" from this? In other words, say I get my breadboard circuit working perfectly, is it now time to create a PCB? If my understanding of circuitry is correct, this is not a trivial process. I would need a CAD program to design my circuit, and it would likely be very expensive to get the design actually fabricated. At least too expensive for simple hobby purposes. Is there a middle ground between breadboard and PCB?
