I have the piezo buzzer working, but it is extremely quiet (barely audible) when connected to the GND and OUT pins.

If I connect the OUT pin to the +5V, it is of the expected volume.


Am I wiring something wrong?

  •  I have the same issue how did you resolve it?

  •  Stupid question, but did you pull off the paper cover?

  • I wish that were a stupid question but in fact  I am so stupid I did not pull the sticker until it later dawned on me.  Of course it now works perfectly.  I felt really dumb!  Thanks for taking the time to get back.
