Ultrasonic Sensor Troubles

[Torben]

In your shoes, I'd try simulating the code to see if it is doing what you expect. At this point we still don't know if the problem is hardware or software.

I don't suppose you have access to an oscilloscope so you can see exactly what's going on?

If you don't have a simulator you can try a trial version of one from https://www.oshonsoft.com/
