Parent has a point. If you can teach your dog that the button is a way to communicate with you when you're out of the house, that would be awesome. I suppose something like having a few signs it can hold when pressing the button, maybe? Training that would be incredibly hard, I'm guessing, but if possible, it would be amazing.
Great idea. My original plan envisioned something like:
- I text into her number while out of the house
- Twilio sends HTTP request to Arduino
- Piezo buzzer sounds
- Kaira has to hold the button for X seconds
- Servo rotates auto treat dispenser
In the end, simplicity won out. That said, those are far from insurmountable challenges.
