Summary of the Circuit
This circuit integrates an ESP32 microcontroller with a 0.96" OLED display and a servo motor, powered by a 5V adapter. The ESP32 serves as the central processing unit, controlling the OLED display via I2C communication and the servo motor through a PWM signal. The 5V adapter provides a stable power supply to all components in the circuit.
