Hey grimham, I'm on the same position of you, do you have the schematic?? We need it so bad... Thanks in advance..

It's probably already been suggested, but why not buy a pre-made module allows you to read range information (versus 1 or 0)? There are a number of options for ultrasonic rangefinders "out there" at online stores like Acroname, Parallax, SparkFun, and others.

Or, you could also use the analog versions of the Sharp IR rangers which provide a 0-5V level depending on distance which can be translated by fairly simple programming into a distance. They're cheaper and in my experience so far, work very well.

Building your own, IMHO, would result in a less reliable solution because you don't have the time and resources to consider and test the myriad scenarios in which the device will operate. You can then focus on the programming to do something interesting with all the sensors.
