thank you so much! I was giving up on my tiny speaker which was soooo quiet. And now it is LOUD. I did use a 2N2222A .. not sure what the A means but it works great

how about bc548 transistor?
how much loudness will i get using the bc547?

[@Nathan1975Liggy]

HMMM cant seem to get this to work using a BC547B.
Trying to boos the sound from a piezo buzzer a little bit for an Arduino EMF detector I made but with the BC547B in line as i this video no mater what way it goes in the buzzer is canstantly sounding

I’ve seen a version of this with a capacitor and resistor added to the circuit. Are these necessary?

So I have the adafruit hooked to a 50w amp. How do I turn the boards volume up. Just volume+ and ground? How will I know when it's up all the way?
