    You're welcome. At least make an effort on your own. There are thousands of PIC & LCD schematics out there. My Unicorn kit can be configured this way.

    Everyday up until his boss discovers this forum


    This project is fairly easy, the only tricky part would be finding instructions regarding the ultrasonic sensor, unless he uses a pre built one that sends out the distance serially.

    How much power? I assume this project does not need continuous polling.
