Hi
I want to use 8051 in such a way that it can detect 4 to 5 different frequencies generated as different inputs from the IR Led. And depending upon different frequencies it should work as different switches.
How can I do that?

You must use active filters for this purpose and output of Active filter is fed to the peak detector. But its a tedious job budy 8O
