A Multifunctional Automatic Dog-Feeder with Bluetooth and Wi-Fi Connectivity

The prevalence of household pets has grown in recent decades. Dogs are the most common, and they provide companionship and protection. Averagely, dogs need to eat at least twice a day. Monthly tablet administration is also required to protect them against infectious pests. It is important to remember that the keeper's hours wasted on these tasks, increases proportionally with the number of pets they care for. Owners may spend far less time on tedious tasks like: feeding, providing water, and medicating pets – by utilizing dispensers. However, there are many important features modern pets need, that are absent from the market's selection of antiquated dispensers. In this work, we present the methodology behind the development of an automated food dispenser. The ESP32 served as the central microcontroller. This automated system essentially dispenses food to dogs, with voice command/ button control, using MIT App Inventor II. It also hydrates pets at predetermined intervals and secretly injects medications into their food. Three different types of monitoring software have been included into the system [Gmail, ThingSpeak and a Database website]. This helps users observe pets' food and water levels. The final product is a combination of the technical hardware and software components.
