KA...
Woher auch?
Gibt es!
z.B. macht es wenig Sinn, über ein Problem zu jammern, aber Code, Schaltplan und die sonstigen notwendigen Fakten geheim zu halten.

Anbei ist der Schaltplan:
Anbei ist C/C++Code (jetzt irgendwie bekomme ich nicht das übliche Feld für den Code, sondern einfach so:

Arduino Engineering Kit Ultrasonic Range Sensor Test
This sketch demonstrates some APIs exposed by the MKR Motor Shield library.
