Posted - Jul 27 2009 : 11:17:54 AM Hi everyone. I created a neat ultrasonic transducer circuit that transmits, then receives and toggles a bit after every transmission. The values for some of the passive components can be tweaked with ease for easy compatibility with your own projects. I use two DPU1640AOH12C 40kHz 105dB transducers for transmitting and receiving. If you're interested in having a look at the document I set up, please feel free. Follow this link: www.electroniclessons.com/ultrasonictransducer.wps.doc I hope you find it interesting and useful. I cheated with the receiver circuit by using op-amps. I've used discrete class A amplifiers in the past, and they work much better. However, this configuration is much easier to work with. Thanks=) Sincerely, Patrick
