Arduino Bluetooth Tutorial HC-05
Can Arduino control a Bluetooth device? Of course, the most common devices are the HC-05 and HC-06. The difference between the two is that the HC-05 can act as a slave and as a master, while the HC-06 can act just as a slave. So don’t bother with the HC-06 ? In this tutorial we will set up a slave HC-05 Bluetooth device and pair it with an Android phone. Then using a Bluetooth terminal found on the Android Play Store, we will be able to send commands to the Arduino and receive confirmation. We will try to switch the builtin LED on pin 13, on and off.
