If you want to drive the LED directly from the microprocessor, connect the anode of the LED to the positive supply through a 100 ohm resistor and the cathode to the digital output. In this case, a Logic LOW at the output will turn on the LED.
Keep in mind that the LED will not light nearly as brightly, and will drastically reduce the range.
Something about that doesn't really sit right in my head, but I'll give it a try anyway. If you could explain, that would be great, otherwise, thanks for your help.
