I’ve been able to create a bunch of projects with various Arduinos, and since they’ve all been stand-alone projects, I’ve never needed to create a schematic. I’ve just been throwing parts together that I know work by themselves, and tinkering with them to work together in various ways. Now, I’ve got to move forward and start documenting these things.
I’ve seen several software recommendations for beginners and more advanced tinkerers for creating electrical schematics, and I’ve seen lots of posts on creating schematics, but none of them really discuss the tips that will make your schematic as close to universally understood as we can get. Therefore, my problem is that when I sit down to one of these applications, I don’t know where to start, and I’m afraid I’ll finish one of these things in a way that makes sense to me, but not to anyone else. Is there a guide/tutorial/list of tips anywhere that could give me some insight into the following:
- A good order in which to draw the schematic (i.e., start with the microcontroller, move to X, then to Y, finish with Z)
- Any conventions about common components (i.e., should there be only one ‘ground’ symbol, or can I throw around as many ‘grounds’ as I need to make it easy to read?
- Any conventions about where to position parts on the page (i.e., do voltage regulators always go in the upper-right corner, or something like that?
- Any conventions about how the traces are drawn? (i.e., anything like ‘never have more than 2 joints in a trace’, or ‘never use anything but right angles’?)
- Any other conventions that I haven’t mentioned.
I’d like to have a little idea of what I’m doing before diving in, but then again, maybe diving in would be the best way to learn. Any suggestions would be greatly appreciated. Thanks!
