Versatile Event Counter by John Becker
--------------------------------------
EPE Online April 1999

This PIC-powered design is capable of monitoring the timing 
of a whole variety of events. The results are displayed using
a liquid crystal display. Input is via a panel-mounted switch, or
a jack-socket to external circuits, or by a microphone - the design
has been found to be extremely responsive to some astonishingly 
low level audio sources detected by microphone.

Displays elapsed time(s) and frequency count. Useful for musicians, 
rowing rates, object counting and so on.

The latest version of the BASIC program listing and PIC 16C84 
source codes are available from the EPE Online Library at
www.epemag.com
