You mean IR "emitters"? (IR LED)
If i understand you correctly, you wish to source current with the
digital outputs. The digouts are from the HC11. There can't source enough
current to light IR LED's.

| What you can do is just like the schematic for the built-in IR emitter circuit. You need to either software generate your wave or do it like the schematic. If software generated, this output would come from a output port on the HC11 to a transistor (...) (27 years ago, 9-Apr-97, to lugnet.robotics.handyboard)
