In this tutorial, we will explore how we can interface the Bluetooth module (HC-05) with Arduino using Arduino IDE. Also, we will build an example project that will turn ON-OFF LEDs by using a Serial Terminal Android application via Bluetooth.

In this project, we'll learn how to interface an HC-05 Bluetooth Module with an Arduino Uno. We'll establish a communication link between an Android smartphone and the Arduino, using HC-05 for wireless control.

The Reyax BLE Connect app (modified for this demo) handles the Bluetooth communication with the RYB2340 module. When I open the app, it scans for nearby Bluetooth devices and shows the RYB2340 in the list. Tapping it establishes a connection. I customized the app's interface by adding two simple buttons—"Relay On" and "Relay Off"—that send the corresponding text commands to the module when ...
