PIC Tape Measure by John Becker
-------------------------------

Everyday Practical Electronics November 1998

This ultrasonic distance calculator uses a PIC
16C84 with a pair of 40kHz ultrasonic transducers
to create a solid-state digital version of the
traditional tape measure. Battery operated, compact 
handheld design.

The EPE PIC tape Measure drives an l.c.d. display to show
the measuring distance in metres as well as feet/ inches.
A special 'mask' function permits screening out of echoes
generated by objects in the foreground.

The latest version of this software is availale from
ftp://ftp.epemag.wimborne.co.uk/pub/PICS/TapeMeasure

The 'tape99' files are also on the EPE CD ROM No. 1, free
with the November 98 issue. 'tape100' is the extended
version allowing 30 measurements to be stored. 

Please refer to the ocnstructional article for more details.
Please check the EPE web site for details of subscriptions,
Back Issues, PCB availability, etc.
