Thanks to this application:
With Arduino Bluetooth connection you can control serial port, led and rgb led.
The codes that should be loaded into the Arduino are in the bottom right of the bluetooth connection screen in the application. Dependent on the sending and receiving formats of shared codes.

NOTE: You must make the Arduino Bluetooth pairing with the phone beforehand or you will not be able to see the Arduino in the Bluetooth device connection interface.

You can calculate the values ​​of ceramic capacitors.
You can calculate Karnaugh maps as 2,3 and 4 digit li.
You can calculate 4 band and 5 band resistors used in electrical and electronic circuits according to color codes or ohms values.
You can learn the pin structure of the electrical, electronic and other integrated devices, connectors and materials.
If you make feedback that may be inaccurate in practice, please rejoice ...

In the Arduino Bluetooth Led interface; It can provide led and rgb led control and the environment of desired color can be illuminated from the color palette.

In the Arduino Bluetooth Port interface; serial port screen can be controlled;
Send and receive value in serial port
Reading values ​​from analog inputs and displaying numerical values ​​in% graphs.
   
There are a total of 9 directional buttons on the Arduino Bluetooth Car interface. It can be used according to the assigned assignments (check the Arduino code.)

You can easily calculate the band colors of the resistors with the ohm value.

The program is designed according to the number of resistance bands most used.
