May 4, 2022 · Adding Bluetooth to your Arduino is the simplest way to give your Arduino projects the power of wireless possibilities. You can get rid of messy wires between the Arduino and the moisture sensor, or even better, you can read the moisture value on your phone directly.

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 ...
