I was thinking npn/pnp but not used them either. I just ordered the subject chip because that's what is used in adafruits tutorial. So the NPN is going to pull the circuit to ground when voltage is applied, somewhat like a relay switch?
If I were to use the chip I have, ALL the unused pins should be to ground?
I think an NPN transister would be much easier as I am only using 1 pin for random sounds to be played.
What NPN specific should I be looking at? I'm sure there's probably thousands out there that do different things.
As always, THANK YOU for your input.
