Push buttons - what's happening when…

I’m ‘attempting’ to learn how to build a standalone noise generating box (probably end up with a bunch of different ones) and saw the PTSD box by Genthalz. It has buttons which trigger more noise/effects when pushed.

I’d just like to understand what’s going one and how it might be possible to implement something similar.

I’m not looking to copy the PTSD - just have the knowledge of how to add push button triggered effects to my breadboard experiments and what might be suitable circuits/effects to add.

If you want help still, i suggest posting more information. :slight_smile:
