This final project discusses the design and development of an automatic cat feeding and monitoring device. The system uses a control mechanism to set the schedule for when the cat food will be dispensed through the Blynk application, synchronized with the current time using an RTC DS3231. When the scheduled time is reached, the servo motor will rotate 120 degrees to dispense the cat food. Once the load cell sensor reads that the weight of the food has reached 30 grams, the servo motor will return to 0 degrees. This load cell sensor gets an average error of 2.422% This control system uses the NODEMCU ESP32 module as the controller, as well as the data transmitter and receiver for Blynk IoT. The device also includes a monitoring system using an ESP32 CAM and its downloader, where the camera can be moved up and down using a servo motor and accessed in real-time. Communication between the ESP32 CAM and Blynk IoT uses the HTTP (Hypertext Transfer Protocol), and the ngrok application is used to create a tunnel from the local device to the internet.
