ultrasonic transmitter and receiver watch

    • Thread Starter

    Does anyone know how to build an ultrasonic transmitter and receiver?

    For the transmitter I've been using the following circuit:

    But not those exact values. However it's still not transmitting!

    and for the receiver I've been using http://www.pages.drexel.edu/~pyc23/u...c_receiver.jpg

    At the end of the receiver I have a motor...that should run regardless if it is receiving a signal or not but if it does receive a signal, the motor should either slow down or speed up.

    Thanks in advance!
