Use of the HC-06 / HC-05 module connected to a microcontroller and through it wireless control (with the help of Bluetooth communication) of 10 electrical consumers connected to a microcontroller - Arduino.
Each button transmits through the Bluetooth the number written on it in parentheses, these numbers should match what you enter in the code of the microcontroller.
You can also broadcast any character / string you want.
Also includes a screen for displaying information transmitted from the microcontroller via the HC06 / HC05 module to the smartphone.
