Buzzer differences

Other Hardware General Electronics
1

Hello, I'm currently working on a project, a small robot car that is controlled by a controller. I'm using a passive buzzer to generate sounds using the tone-function, but I have the problem that the buttons of the controller "suddenly" stop working after I have used the buzzer. I'm now worried that I have bought the wrong one.

I'm aware that there is an active and a passive buzzer and I understand the difference. But now I have seen buzzer modules with 3 pins instead of 2 and some that are on a circuit board. What is the difference and which buzzer is needed for which application? Or does none of this matter?

Thanks for the answers!

Post your code. If you have used delay() or other blocking methods to control the time the buzzer sounds then buttons etc. may be unresponsive. A buzzer may also require a flyback diode across it to prevent instability.
