Viele Servos mit Arduino steuern

Hallo Stefan,
danke für die schnelle Antwort. Ich habe auch schon ein Sketch im Forum opendcc gefunden.
Hier der Sketch werde ihn demnächst ausprobieren.

// Arduino DCC Servo and Function Decoder.
// Author: Author: Ruud Boer – January 2015
// This sketch turns an Arduino into a DCC decoder with max 12 servo motor outputs combined with function outputs.
// The DCC signal is optically separated and fed to pin 2 (=Interrupt 0). Schematics: http://www.mynabay.com
// Many thanks to http://www.mynabay.com for publishing their DCC monitor and -decoder code, which is used in this sketch.
//
// Important Change:
// This sketch from Ruud Boer was changed by lordbrummi in April 2016
// Now you can connect a PWM Arduino Servo Shield with 16 possible servos and adress them with DCC adresses

Hi Stefan,

habs gestern auch schon gefunden. Funktioniert einwandfrei diese Lösung. Will eine Weichensteuerung für Sohnemann bauen mit Touchdisplay zum schalten der Weichen.
