I am quite new to hardware hacking, and have chosen to use the Arduino for my first project.
I am attempting to build a cat deterrent, something akin to this. I have figured out detection, and now realize that I need to use an ultrasonic transducer to produce the 'blast' that I need.
However, I am clueless as to how I would interface one of these with an arduino.
Does anyone have any advice?
Thanks for helping a newbie out.
