I am trying to build a device which will use an ultrasonic sensor (polaroid 6500 ranging module). This device will generate a sound which the user hears through an ear-piece when an object comes within range.
Preferably the sound would become more intense as the object comes closer to the user.
Also, I don't have access to a microcrontroller and need to use only analog circuits (no programed chips allowed)
Thanks for the help
