Signal Input for WavTrigger

I’m wanting to trigger a sound but this whole project’s intentional challenge is to not use a microcontroller.

I have a trigger set to edge and is grounded with a button but when part of the circuit is off, it grounds itself and starts playing.

Can I just set a voltage regulator between it and the board and trigger it with a ~3.3v or ~5v signal? Or is it more picky than that?

Eeeyyy! So setting it to active works just fine! Sorry, I have no clue how this stuff works so I’m figuring it out as I go!

Nice :smiley:
