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 ...

Bluetooth can be added to any Arduino using either a shield or by connecting a Bluetooth transceiver with a serial connection. It typically costs between $10 and $20 to add Bluetooth to an Arduino depending on if a shield is used (more expensive) or if …
