Hello everyone. I have made a wav player with my arduino uno, and have 3 buttons to control play/pause, next track, and volume.
I have it currently hooked to 1 piezo speaker and it is good but quiet.
I have another speaker that is a headphone speaker that doesn't make any sound, seemingly not enough power to it.
I have a AA battery pack for the boosting power.
I have an RCA 2N3053 transistor and a Helitrim 58-247-0 potentiometer.
I am trying to have the audio from pin 10 go through the potentiometer and transistor, out to the speaker, amplified.
I can't figure out the correct circuit to make with the equipment I have,
Thanks in advance for any help.
Here is a few pictures of the setup.
