#define setdebug  // einschalten, um Infos über USB-VCP "Serial Monitor" zu erhalten 

Weichenantrieb mit Servo
  Compiler: Board: "Arduino Micro" (ATMEGA32U4)

Funktion:
  an drei Pins (2,3,4) kann Servoposition gestellt werden
  davon ein Testpin (2) für Mittelstellung
  Pulsfolge an Servo wird nach t Impulsen beendet, um
  Durchbrennen des Servos beim Anschlag zu verhindern
  Pulsabstand ist 15 ms
  Prellen wird ignoriert, nur mit anderem Pin wird wieder gestellt
  <servo.h> ist ungeeignet, weil Pulse nicht abgeschaltet werden können

Programm testen mit dem Serial Monitor von Arduino (unter Werkzeuge)
  Serial Monitor einstellen auf: Autoscroll; Kein Zeilenende; 115200 Baud
  #define setdebug  // einschalten, um Infos über USB-VCP "Serial Monitor" zu erhalten 

Pins am Pro Micro:
  Pin 9: Pulse an das Servo
  Pin 2: Test auf Mittelstellung 90°
  Pin 3: vom Taster, Weiche auf  0°
  Pin 4: vom Taster, Weiche auf  180°
