I finally got around to experimenting with a 555 IC. Despite my post from several months ago, I decided to not use the schematic offered to me for use of a normally closed switch (great circuit, though; works perfectly) and will instead use a NOT gate (I still am constrained with a normally...

Sadly, the switch cannot be changed. Thank you for this possible solution despite my request to not post a solution. I never would have stumbled across putting the switch there. If you hadn't posted the explanation, I'd never had figured out why that could possibly work; I'm still not used to...

Even though the button is normally closed (button in the diagram pressed closed), the buzzer will still go one the button is pressed (trigger open)? I thought that would make the circuit buzz when initially powered and then not buzz again until the button was pressed (opened) long enough to...

I'm sure there is an easy solution to my problem, but I very little electronics background and don't yet have a breadboard to even experiment on. In fact, it was only two days ago that I learned a 555 doesn't need to (or can) be programmed by a computer to use. I want to make a buzzer that...
