This app is designed to test Arduino's HC-06 and can be used to control electronic circuits via Bluetooth.

The HC-06 Bluetooth module allows Arduino to communicate with other devices via Bluetooth. It allows the Arduino to connect to and exchange data with other devices such as a smartphone, computer, or other devices. The HC-06 functions as a serial port, allowing you to transmit and receive data. You can manage and supervise your project by using a serial terminal or a Bluetooth customized application on your computer or phone. When serial data is transmitted by a master Bluetooth device, the HC-06 Bluetooth module can receive it.
