Hello.

Pardon me for such an easy question.  I have a pair of sonar =
transmitters and receivers (400ST160/400SR169) and I would like to play =
around with sonar.  The datasheet is of no help whatsoever and the =
schematics I've found on the web are quite complex.  Since I am new to =
the electronics parts and still learning, I like to start simply on a =
breadboard.

I think I understand the transmitter fine.  It is the receiver I am =
having trouble with.  My question is this:  how do I simply wire this to =
a breadboard where I can read the output with a Pic chip?  I'm thinking =
I get a voltage output somehow, so I would guess that I can read it with =
the A/D converter fine.  I'm having trouble, frankly, understanding how =
it works (only two leads) and how to wire it up.

Any help or links greatly appreciated. =20

Cheers,
Lindy
