Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes an Arduino Nano as the central microcontroller, interfaced with various sensors, input devices, and communication modules. The circuit is designed to capture input from PS2 joysticks, tactile switch buttons, and potentiometers, display data on an OLED screen, communicate via an NRF24L01 module, and provide audio feedback through a piezo buzzer. The MPU-6050 sensor is included for motion tracking. The circuit is powered through the Arduino Nano's 5V output, and ground connections are distributed across the components.
