This project presents an engaging, DIY desktop pet built around the ESP32 microcontroller. The creation utilizes key components such as a 0.96-inch OLED I2C Display Module for vibrant visuals, an ESP32 development board as the core processing unit, a small lithium-ion (lion) cell for power, and a TP4056 Charging Module to ensure convenient and reliable charging. Furthermore, the U8g2 Library plays a crucial role, enabling the display of captivating animations and implementing the underlying logic, resulting in a truly interactive and dynamic user experience.
