Cat Food Access Control
By Emanuele Signoretta on March 26, 2020
This project goes over the process I used to create an automated cat food bowl, for my elderly diabetic cat Chaz. See, he needs to eat breakfast before he can get his insulin, but I often forget to pick up his food dish before I go to bed, which spoils his appetite and throws off his insulin schedule. This dish uses a servo motor to close a lid over the food between the hours of midnight and 7:30am. The NodeMCU ESP8266 microcontroller’s Arduino sketch uses Network Time Protocol (NTP) to control the schedule.
