Spent the last 30 minutes trying to locate a Piezo element or ?? that will output a frequency of 30-60khz.
Going to or hope to connect to a PIC with an amp.
But locating a Piezo unit to produce sound.
I see resonant frequency but isn't that the element frequency output?
maybe I is stupid in this audio stuff?
I see lots of elements that have 3 wires and only requite one transistor to drive it.
Need some direction.
