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.
I am having this same issue with the buzzer that came with my Konnected kit as well. I bought another buzzer and it works as I would expect.
