OK, verification done, the voltage is correctly switched to 5V with the touch
sensor. I probably programmed a wrong port# !
But clearly the 5V is enough to power the US transducers (probably with reduced
range)

| (...) Sorry Brian, you are right! my ageing ear was not able to get the much weaker "ping" at first. My interpretation (to be confimed) is that the US sensor goes on working even if not configured, but some sensor modes don't provide the 9V supply (...) (19 years ago, 22-May-06, to lugnet.robotics)
