kunna ändra öppningstiden på magnetventiler och även intervallen mellan öppningstiderna
tiderna ligger i variabeln ValveTime[]
har en rutin som skriver ut tiderna på en display och man kan med tryckknappen flytta cursorn mellan de olika positionerna
behöver hjälp med att förändra värdet i positionen med encodern hittar ingen tutorial för detta
någon som kan knuffa mig i rätt riktning?
