Right. The traditional and easy way to get a bunch of LEDs (or equivalent) to light up equally is to put them in _series_. Then you only need _one_ current limiting resistor (or fancier circuit). Can you trade in your 5V supply for a 24V supply? - Larry _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
