Sorry but this is very spread question...

Idea is that You use a IR transmitter (diode or other emiting IR light - IR light has a spectrum so this is next thing)

And You have a modulation circuit ... generator that generates a base frequency and modulation circuit that modulate a base freq....

Simple devices use a direct drive to IR LED and there is no base frequency generator...

...
Next are standards of modulation ... like RC5, RC6 ...

Please be more specyfic...

B regards
