I did this with a PIC a few years ago. It's not all that hard, but you need a 'scope for sure. I used 4049's to driver the transducer, sending 10 cycles at 40kHz. I actually got mine to work a little better than the Ping module, but at four times the size and twice the price. :-0 It was really fun though, I learned a lot. If you would like more details, send me an email and I'll dig up my old PIC code and schemtic if I still have it.
