This code is for reading the K-Linke in Cars. With this code you can read sensor values, troubleshoot codes and more. It is compatible with ISO9141 and ISO14230(KWP slow and fast) protocols.
I have shared schematics to communicate with the car. You can use these schematics or you can make another one. I used Arduino nano and ESP32 C3 as microcontrollers, but you can use another microcontrollers like STM32, ESP8266 and much more.

I will share more information about K-Line protocols and communication later. Stay tuned 😉.
