· Pin Diagram of IR LED. An IR LED is a type of diode or simple semiconductor. Electric current is allowed to flow in only one direction in diodes. As the current flows, electrons fall from one part of the diode into holes on another part. In order to fall into these holes, the electrons must shed energy in the form of photons, which produce light. It is necessary to modulate the emission from ...
Block diagram of the system: Basically, a remote control works in the following manner. A button is pressed. This completes a specific connection which produces a Morse code line signal specific to that button. The transistor amplifies the signal and sends it to the LED which translates the signal into infrared light. The sensor on the appliance detects the infrared light and reacts ...

· As you can see from the block diagram above pin 1 is your output (far left on your picture). The receiver sinks pin 1 when the correct carrier is detected. But it can only sink a maximum of 5mA so you must limit the diode current if you hook one up directly to the output. I would use a buffer stage of some sorts. Hint: you could probably make one yourself with a PNP transistor.
