The parallel port has less than 12 outputs. But i need to control more than 12 devices such as to control more than 12 LEDs separately . So any ideas how to do this?

Look up a book on google called "Parallel Port Complete: Programming, Interfacing, & Using the PC's Parallel Printer Port" by Jan Axelson. It will tell you -everything- you need to know about interfacing with the parallel port.

Another one to check out is "MY EXPERIENCE IN PARALLEL PORT INTERFACING" by Bibin John.

If you want to have over 12 available bits for On/Off you may want to start looking at the serial port or really USB. One problem with the Parallel port is it is becoming more and more obsolete and not showing up on new motherboards, actually the serial port is also going away.

Jan Axelson, as mentioned has some great material out there for the Parallel Port.

Did you want to write your own code for port communication?

Also, if you Google around for those Christmas Light Shows you should find some good material to read.

Additionally Eric Gibbs here in these forums has written some nice software for parallel port communications.
