Hello, I'm looking for something that would is very high pitch and would work great as an alarm that are compatible with an Arduino.
Please provide an Amazon link.
Sorry I do not use Amazon. I can lead you to a siren that uses a 50 HP motor or a pizzo annunicator that uses mills, all controllable with an Arduino. I would suggest you start by defining what you are trying to do. I have as much chance of answering this as to what color lipstick your mother wore the last time you saw her. This response is to help you get started in solving your problem, not solve it for you.
Good Luck & Have Fun!
