Johan,Je wilt de standen weten omdat dat de twee hoeken zijn waartussen de servo heen en weer gaat?Dan kun je die twee standen in de code opnemen voor de servo aansturing. Klopt dat?Oftewel: de servo moet 'getuned' worden.
Dat kan ook simpeler. Momenteel ben ik juist bezig met een programmaatje hiervoor.Dat vraagt eerst een pinnummer waar de te tunen servo aanhangt. Daarbij worden de twee hoeken op 75 (LOW) en 105 (HIGH) graden gezet, 15 graden om de 90 dus.Vervolgens kun je, in de serial monitor door op + en - te drukken de waarde van LOW met één graad verhogen of verlagen.Met 'C' wissel je van de ene hoek naar de ander.Met 'S' sla je de waardes op in het EEPROM en kun je een nieuw pinnummer opgeven.Code: [Selecteer]...
