Using a bluetooth dongle to control an electronic signal

[snap61]

Hey guys, me and a friend are planning a project which involves syncing a phone with a battery powered bluetooth dongle which which should ideally produce an electrical signal to a buzzer. I am looking for bluetooth products I can disect for to create a prototype, but any help in the realm of bluetooth would be great!

Hi snap61,

Welcome to you !

An bluetooth dongle is not something self contained. A processor must interface it.

So the minimum setup will be:

USB Dongle <-->Processor-->Buzzer and a software.

However for your device the USB option is probably not the best one as you need to have all the documentaion to wrote a software driver (as used on a PC) to be implement on a small microcontroller with very few horsepower.

By googlink a bit you can find bluetooth modules dedicated to be connected on small microcontroller, exemples here under:

As the hardware will be very easy to set the main job is to wrote a firmware for the microcontroller.
