Example of analog comparator usage

The layout can be used instead of the sensor A/C (line detection sensors, opposite). On one input we give the signal from the sensors, on the other the reference results, which will be the threshold (e.g. with a potentiometer). At the output we receive a digital signal, which we can connect with a microcontroller pin. An corresponding layout can be created to compare distances.
