I have a buzzer that is activated by a low voltage momentary switch. Of course, when the switch is closed, the buzzer sounds and when released, there is no sound. I want to bypass the analog buzzer and send a BLE signal to the iPhone and have the iPhone make the sound. This can then go to the earbuds and have the sound private.

Help

What microController do you plan to use ?

Anything seems possible when you don't know what you're talking about.

@will I think he said he wants to close a contact and emit a BLE signal, not sure a mcontroller is even needed, this unit says no controller needed.

@will His post is confusing, the Topic is totally different from the body of the post.
