Hi,
I want read precise time elapsed between two flash of a red led and show this time on a 8/16 char matrix display. The value has to be very accurate. Time range goes from 0.2 sec to 15 sec.
I would like do this by a 16F84 in basic language (picbasic pro compiler)
Im a VB programmer and Im a newbie in a microcontroller programming
Any suggestion for code and circuit for phototransistor ???
Thanks
