Circuit Documentation

Summary

This circuit integrates an Arduino UNO microcontroller, an HC-05 Bluetooth Module, and an RGB LED Strip. The Arduino UNO serves as the central controller, managing the RGB LED Strip and communicating with external devices via the HC-05 Bluetooth Module. The RGB LED Strip is controlled through digital pins on the Arduino, allowing for color changes and effects. The HC-05 Bluetooth Module enables wireless communication, allowing the Arduino to receive commands remotely.
