Circuit Documentation

Summary

The circuit in question is designed to interface an Arduino UNO with a touch sensor, an OLED display, a servomotor, and a buzzer. The Arduino UNO serves as the central microcontroller unit, managing input from the touch sensor and controlling the display, servomotor, and buzzer based on programmed logic. The touch sensor provides user input, the OLED display offers a visual interface, the servomotor enables mechanical movement, and the buzzer can generate audio signals.
