Additional Notes

• The provided code is a template and does not contain any specific logic for Bluetooth communication or other functionalities. It needs to be populated with the appropriate setup and loop code to handle the Bluetooth module's data transmission and reception.
• The D0 and D1 pins on the Arduino UNO are used for serial communication with the Bluetooth module. Care should be taken to ensure that the serial communication is correctly configured in the code to match the Bluetooth module's requirements.
• The Bluetooth module requires a power supply connected to its vcc pin, which is provided by the Arduino UNO's Vin. Ensure that the voltage levels are compatible.
• Proper grounding is essential for the stability of the circuit, hence the gnd of the Bluetooth module is connected to the GND of the Arduino UNO.
