Bluetooth 2 Relays Control Pro is a simple Android application that allows users to remotely control two relays or devices using an 89c2051 Micro-controller and an HC-05 Bluetooth Module. Developed by Hobbyprojects.com, this app provides a convenient way to control devices wirelessly.

To get started, users need to ensure that their HC-05 Bluetooth Module is paired with their mobile device. The default password for pairing is "1234" or "0000", as stated in the Bluetooth module's manual.

Once the pairing is complete, users can control the relays by pressing the ON or OFF buttons for each device. When the ON button is pressed for Device 1, the app sends the data "A" to the Bluetooth Module, which then turns on the corresponding relay. Similarly, pressing the OFF button for Device 1 sends the data "a" to turn off the relay.

For Device 2, pressing the ON button sends the data "B" to turn on the relay, while pressing the OFF button sends the data "b" to turn it off.

Bluetooth 2 Relays Control Pro offers a simple and practical solution for remote device control, making it a useful tool for various applications.
