Everything that has been done within the scope of this research is aimed towards designing a device with a solar voltage source, that is capable of directly and automatically feeding a pet animal by adhering to the schedule and conditions pre-determined by the user. The design utilizes the ESP8266 Wi-Fi module as a controller that receives weight data about the pet’s food inside a container. The Arduino also controls a servo that opens the container based on the parameters set by the user via a Blynk app in a smartphone. This system includes a relay to switch from a wall socket adapter power supply to a battery connected to a solar panel. The obtained results satisfy the purpose of the research. The device was able to operate well using the utility grid and it can last for two hours solely on a 12 V 6Ah lead-acid battery. The device is 100 % accurate in adhering to the user’s schedule, responding with an average delay time of 1.4375 seconds between the Blynk application to the ESP8266 system.
