Circuit Documentation

Summary

This circuit integrates an Arduino Nano microcontroller, an HC-05 Bluetooth module, and a KY-023 Dual Axis Joystick module. The Arduino Nano serves as the central controller, interfacing with the Bluetooth module for wireless communication and the joystick module for user input. The circuit is powered by a 5V power supply.
