Hi!
I am integrating a piezo sounder into my project. As for now, I have one of the digital output pins directly connected to the piezo. It works, kind of. Like I can hear it. barely. It's a 12v transducer and obviously it is under-powered. I do have 12v power supply so the question is not how to add a step-up. The question is how to commutate 12v with 3v?
It is a n00b question, but it is my first project that actually involves not only programming and connecting components but actually soldering
I googled and read this forum and it seems I need a mosfet. But exactly which one? 2N7000 looks like the cheapest one, will it work???
Also, there are a couple of post mentioning it worth adding an inductor into the circuit to increase the output from the transducer. Which inductor? Where??
If anybody could draw me a circuit, I would really appreciate it.
Thank you,
Ann
