In this project, we will learn HC-06 Bluetooth Module to Android Mobile Wireless Data Communication with AVR ATmega32 microcontroller and LED Display. Here, we will connect the HC-06 Bluetooth and Android Mobile through Bluetooth. And, we will send data wirelessly from HC-06 Bluetooth to Android Mobile. The transmitted data is also displayed in 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 ATmega32 microcontroller takes place through UART serial communication protocol. The HC-06 Bluetooth Module and Android Mobile are connected through Bluetooth. The ATmega32 microcontroller will send the string “ABLab Solutions” to the HC-06 Bluetooth Module. One character is sent at a time with a delay of 500ms. The HC-06 Bluetooth Module transmits the received characters wirelessly to the Android Mobile and the Android mobile displays the received characters in the Bluetooth Terminal App window. The microcontroller will also display the ASCII value of the transmitted character in a 1X8 LED array.
