Podłączyłem sobie impulsator 20sto impulsowy do arduino uno ze strony:
https://elty.pl/pl/p/Modul-z-enkoderem% ... Y-040/1155
I faktycznie ma 20 "kroków"
Niestety arduino liczy mi podwójnie ...
Tzn jedno cyknięcie to dolicza kolejne 2 zamiast 1.
Ma ktoś pomysł co robię źle?

aState = digitalRead(outputA); // Reads the "current" state of the outputA
// If the previous and the current state of the outputA are different, that means a Pulse has occured
if (aState != aLastState){
// If the outputB state is different to the outputA state, that means the encoder is rotating clockwise
if (digitalRead(outputB) != aState) {
counter ++;
} else {
counter --;
}
Serial.print("Position: ");
Serial.println(counter);
}
aLastState = aState; // Updates the previous state of the outputA with the current state
}
