I am working on a project where we have two transducers communicating with each other. The first transducer will send a signal that is generated into the water for the second transducer, when the second one receives it, we are thinking of rectifying the signal and have it connect to the Arduino analog input. We are new at this and don't really know how to program the Arduino to recognize the unique signal by the time between its rising edges. Any ideas on how to program this? Any help would be much appreciated! Thanks
