Ultrasonic HC-SR04 dog anti-poop sketch/project

fun!

Much to my enjoyment, the dogs don't share your opinion. It even looks scary to them before the siren and lights are triggered. Even my wife is kind of warming up to it. She's starting to believe there's something to my hobby and it's not all about getting high from sniffing solder in the basement. Which means more toys for me. What other household problem can I tackle next?
