Ultrasonic distance measurement( 28015) and Parallax (P8X32A-D40) microcontroller

Alhilalm

Hello

I am trying to measure the distance of human body using Ultrasonic distance measurement( 28015) and Parallax (P8X32A-D40) microcontroller. Also, I am using SimpleIDE software to program the microcontroller. I need the ultrasonic to start triggering from 3 feet and I need a pulse counter to make sure I output only 0-1 V. But I have no idea how to write the codes or how start, So can please someone help me with that??

Have you checked the Parallax Learn site, as probably there's some code samples or ideas over there. Search for "PING"
