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!
