Hello I am trying to protect goats with a PIR sensor and alarm, but am having problem with the bluetooth speaker.
A neighbor recently found 4 adults and one newborn goat pleasure killed by a pack of wild (feral) dogs and I am resolved to figure out an alarm that would drive away these pests without having to pull all nighters posting up with guns waiting for these poochies. Then I can make a few for the local farmers and hobby ranchers to help them out as well.
So far I have worked out the use of PIR sensors around the pen that are working great with my off-brand mega board, both of which were easily available from a nearby Fry's Electronics. However I'd like to implement either a loud noise or a high pitch noise to drive away these dogs. As I'm a newcomer to Arduino in general, I couldn't really get a speaker or buzzer that would both meet my standards and the board's capability for output. I got a Bluetooth transmitter with a Bluetooth speaker to compensate for that problem, but am a bit confused on how to proceed as I can't find much info online about folks using a Bluetooth speaker as an output. The issue I'm having is that I can't connect the transmitter to the speaker.
My only experience with electronics is with remodel construction and wiring my own home. My only arduino experience is a few sensors with my aquaponics plants so far but this is my first major effort. Have any of you folks had success with using bluetooth in your alarms for your IoT systerms? Hope I'm posting in the right area. Will appreciate any help and have a fantastic day
