I'm using this circuit shown on this page: http://www.leang.com/robotics/info/articles/minison/minison.html.
With the Ultrasonic timing diagram looking like this:
I would like to attach this to a PICAXE so I can determine the "Time Of Flight", therefore allowing me to create a distance sensor.
Seeing as the echo line stays high, and drops low on an echo (as shown in the diagram), how would I go about doing this on a PICAXE?
Thanks in advance,
Jon
