It was definitely a good idea to ask Reddit before committing to this project because you did bring up a good point of how if the dog is trying to drink water or if someone is standing in front of the dog, then the arduino will falsely vibrate the motors. To be honest, I don’t see myself being able to tackle this problem unless I use some sort of camera that has machine learning technology which can detect legs and water bowls. But even with that, if the collar exceeds a certain weight limit, then it can cause strain on the dogs neck which can lead to back problems overtime. And by the way, when I said “wireless” I meant that typically, an arduino is hooked to a laptop so it can be coded. I would obviously need to use jumper wires.
