In this project, we will learn Android Mobile to HC-06 Bluetooth Module Wireless Data Communication with AVR ATmega16 microcontroller and LED Display. Here, we will connect the HC-06 Bluetooth and Android Mobile through Bluetooth. And, we will send data wirelessly from Android Mobile to HC-06 Bluetooth Module. The received data is displayed in a 1X8 LED array.

The communication between HC-06 Bluetooth Module and Android Mobile takes place through wireless Bluetooth technology. And the communication between HC-06 Bluetooth Module and ATmega16 microcontroller takes place through UART serial communication protocol. The HC-06 Bluetooth Module and Android Mobile are connected through Bluetooth. Data is transmitted wirelessly from the Android mobile (i.e through the Bluetooth Terminal App) to the HC-06 Bluetooth Module through bluetooth. The HC-06 Bluetooth Module receives the data and transmits it to the ATmega16 microcontroller through UART. After receiving the data, the ATmega16 microcontroller will display the ASCII value of the received character in a 1X8 LED array.
