Hi, I’m tinkering with a Ping))) sensor on the end of an extender.
I have a question regarding logic levels and what others have experienced.
When I trigger the distance measure, I see a nice initial pulse, but the variable width reading returned is only at 400mV, vs 3.3 or 5 for the initial pulse.
I get the same results with wall wart power, and for USB power, and with and without a level converter in the signal path.
Is this what others have observed or do I need additional circuitry?
