Hello I'm wondering whats the best forum for circuit creation?

I'm currently working on a circuit on a peace of paper and pen and I have almost everything planned, but one problem...

How do I save memory of a boolean?

I'm creating a control panel for a simple security system and I know how to get it so I know if the system is armed, but how can I store a simple boolean saying the alarm should sound when triggered and is able to reset to 0 if I reset it/power off.

I was wondering if it was best to use some sort of relay or a chip to help with the dirty work and I was wondering if there was a good forum that any of you use if you perhaps like to create circuits and write software as I do.

Thanks, Ajm.

A flip-flop can be used to store a single bit. An SR (set-reset) latch could be "set" by the alarm sensor to make the alarm sound, then "reset" by the user to switch the alarm off. The popular 555 timer IC can be used as an SR latch.

Wow thanks! It didn't make much sense when I first looked at some of those schematics, but after a while of plenty of Google search and examples it started to sync and made sense, so now my blue prints are done.

Thank you!

(I just hope I can fit my project in small one project box. D: )

Check out FPGA's if you're interested in hobby electronics. The simple ones can be had for cheap ($50-$100 bucks), and you can cram a lot of digital logic on them.

Or Arduino.

Ti used to sell their Launchpad kits for under $7. Good value if you want to experiment. Not sure if that offer still exists.

Hey thanks! This website is very helpful in the written tutorial section and I've been viewing the video tutorials too which are pretty neat.

Thanks everyone else, but I already have a [color="#1C2837"]Arduino board and I want my first project using a chip to be more of a learning curve then having to write code to a controller that does everything, plus I want my circuit to be as small as possible, but next time I'll use it to do much more advanced logical stuff if it will greatly speed up results.

Also Hack a Day has launched their new forum. Seems to have a healthy ecosystem for such a new forum.
