I believe you have the IR output indicator confused with the emmitter
driver. The red LED indicates that IR output is being transmitted. (That
is...if you have an external IR LED attached to the HB.) There is a header
for it.
You can get a detector from Radio Shack.

| Is the ir emitter on the handyboard just a standard red led? Is it efficient at emitting in the IR range. Are there better emitters? I want to build an emitter and detector set and have studied the multiplexing circuit posted. It uses the same LED. (...) (26 years ago, 24-Jun-98, to lugnet.robotics.handyboard)
