Can someone give me the schematic diagram and the details of building a complete functioned ultrasonic sensor with the transmitter and the receiver alone??
How to build the PING ultrasonic sensor??
Please help me out on this.
Thank you very much.
Building your own copy of the PING))) would be impossible, even with the schematic, since you wouldn’t have the firmware. Of course, the schematic is not available either. You can always Google for Ultrasonic Sensor Schematic and build your own using that information. I have found that there are many schematics for these types of sensors.

The Ping sensor has on-board intelligence that lets it put out a 'Pulse' that represents the echo-time to the nearest object. This 'Pulse' can then be read easily by the BS2 with a "PULSIN" statement. This makes it easy to interface a Ping to a BS2 using only a single I/O pin (and Vdd and Vss to power the Ping, of course).
Really, Parallax sells this at a very low price for what you get. Rolling your own is going to be either more expensive, less accurate, or both.
