Hallo,
Met een omweg werkt dit maar krijg het niet netjes geprogrammeerd.
de bedoeling: knop indrukken timer loopt 3600 sec, daarna stepper langzaam aan.
Knop los stepper langzaam uit.
if (digitalRead(8) == HIGH) {x=1500000; kan mij inziens anders
En als de knop los is en timer is afgelopen gaat de motor toch even langzaam uit.
geen groot probleem ......maar ja
wat kan ik verbeteren ?
