Could a hardware expert (Fred?) please give a more definitive answer to this?
What value resistor should be used? After extensive IR use with just an IR led
and no resistor my transmission circuit eventually died... I guess I burnt out the
transistor but not being a hardware person I don't really know for sure.
Thanks,

| (...) o Hi Did anyone receive an answer to this. I ant to connect a Radio Shack (276-143) IR LED to the IR output and am wondering what resistance to use. Also, I saw a design in Mobile Robots..Inspirition where they use two IR LED (one on each (...) (26 years ago, 24-Feb-99, to lugnet.robotics.handyboard)

| You can connect an IR LED to it. Maybe you may need a series resistor to limit the current through it as well. Basically, the IR LED acts as a transmitter (the same round thing in front of your remote). The demodualator is not a transmitter...it is (...)
