 How to code Bluetooth module with Arduino?

• Writing the Arduino HC-05 bluetooth module code:

1. void setup(){
2. Serial. begin(9600);
3. QuartzBT. begin(9600); //Default Baud for comm, it may be different for your Module.
4. Serial.println("The bluetooth gates are open.\n Connect to HC-05 from any other bluetooth device with 1234 as pairing key!." ); }

• How does a Bluetooth module work?

    They utilize radio waves to establish connections and enable communication between devices such as smartphones, computers, IoT devices, and more. Bluetooth modules operate on specific frequencies within the 2.4 GHz range and provide reliable, low-power, and secure wireless connectivity.
