A module with line sensors designed to work with the Kitronik kit. It has two sensors in the form of phototransistors that generate an analog voltage that can be read by the microcontroller. The module is equipped with a 4-pin connector (3V, 0V, L, R), which allows for power supply and reception of signals from the sensors, and the output voltage changes depending on the detected surface, which allows it to be used not only with the Kitronik kit, but also with platforms such as Arduino or Raspberry Pi Pico.
