I am new to this and new to tinkering. SO please be patient if possible.
My neighbor's dog has a barking problem. We live in an apartment. Their door is directly across the hall from my apartment.
What I noticed is that he stops barking when he hears a loud car horn. What I did was wired a car horn to a transformer and when he barks I press a button. What I notice is that he stops barking for a good 2 hours. During this time, I am able to concentrate on my work. By the way. The neighbor is not home when this is happening.
What I would like help with is wiring an Arduino to sense the noise and activate the horn for 2 or 3 seconds.
I do not know where to start. So if you can help me start, that would be nice. Thank you!
I have an Arduino Uno and mini. I have a 12v power supply and a siren.
