Circuit Documentation

Summary of the Circuit

The circuit in question consists of three main components: a 0.96" OLED display, an ESP32 One microcontroller, and a pushbutton. The OLED display is used for visual output, the ESP32 One serves as the central processing unit with connectivity and control capabilities, and the pushbutton acts as a user input device. The circuit is designed to allow the ESP32 One to control the OLED display and read the state of the pushbutton.
