What are Bluetooth Modules?
Bluetooth Modules are compact wireless communication boards that enable short-range data transfer between a microcontroller and another device like a smartphone or computer. They communicate over UART serial protocol and pair like any standard Bluetooth device. A common example in Indian college robotics projects is using HC05 to control a robot car wirelessly from an Android app without any WiFi network or internet connection needed.

How to Choose the Right Bluetooth Modules
Choose HC05 when your project needs both transmit and receive capability — it works in both master and slave mode. HC06 suits simpler applications where the microcontroller only needs to receive data from a phone. For low-power wearable builds, a BLE 4.0 mini Bluetooth module is the right pick over classic Bluetooth variants. One practical tip — always set the HC-05 baud rate to match your Arduino serial speed before pairing, as a mismatch causes garbled data and failed communication on the first connection attempt.
