Basically the title says it all. I'd like to make a micro buzzer that uses a 3.5v coin battery as power that will start buzzing after a minute. I know I can use the 555 chip (I think that's the number) and a resistor as a controller for the timer, but I'm just not sure how to make it all fit together. If I have a circuit diagram I can make it go, but I've done a lot searching and haven't found anything that is small enough.
Any ideas or circuit diagrams that you know of that does what I am looking for?
I know enough about electronics to get in trouble but when it comes to component design I'm a bit lost. I've tried using online circuit testing/design platforms but haven't had success.
