Bluetooth Technology
In this tutorial, we going to discuss how can we interface a microcontroller with the Bluetooth technology. The Bluetooth will work with an Arduino board through the serial communication. The data is received to the Arduino with the HC-05 Bluetooth module through the serial communication and the LED’s will turn ON/OFF according to the receiving data. There are different types of Bluetooth modules are available in the market, but here we are using the HC-05 Bluetooth module because it is commonly used.
