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.
