Examples:

If it is a two pin bicolor LED: connect a resistor in series with one of the=
 pins, then the loose ends of both th eresistor and LED to one PIC pin each.=
  To torn on one color hold one pin highn the other low.  For the other=
 color switch high/low.

If it is a three pin bicolor/tricolor LED: connect the middele pin to GND. =
 The other pins to one PIC pin each whith series resistor.  To turn on one=
 color hold one pin highn the other low.  For the other color switch=
 high/low.  For a mix of both hold both high.

Resistor value in all cases about 330ohms.

Hej Robert Wade. Tack f=F6r ditt meddelande 08:15 2002-09-06 enligt nedan:
