Ping ))) Receive only mode?
I have been looking at toys that take ultrasonic sounds from bat screeches and down-convert (resample) them to human hearing range and was thinking of a detector project with the Ping. Is there any way to turn off the transmitter (hardware trace cuts are fine) and just have it listen and log when sounds are heard?
I'd like to differentiate from them as well; e.g. in frequency if possible.
Didn't see anything on this via searches, so thanks in advance!

You need an ultrasound to audible sound converter. There have been DIY versions of this in the past. I remember one in Popular Electronics years ago. Try Googling.· Here was one article I found: http://bertrik.sikken.nl/bat/convert.htm.

Thanks for the link - I have found a lot of analog bat freq down-converters, but want to keep this one in the digital space.
Maybe I will do a mic input for Arduino, and create a frequency counter via an ultrasonic receiver mic.
