What hardware do you have or can make? LED output is simple, but what about the human presence detection? Any ports in your computer? What did you try to find? There are a lot of project of this sort everywhere, including CodeProject.

Also, are you going to take into account the power consumption by a computer? :-)

Solution 1

Controlling LED's: I/O Ports Uncensored - 1 - Controlling LEDs (Light Emiting Diodes) with Parallel Port[^]

"any suggestion what hardware should i use for detection of human presence?"

Camera, or better still use a PIR[^] - the type used in burglar alarms should be cheap but effective.

Solution 2

I would use a microcontroller, see, for instance: "Motion detection alarm using a PIR sensor module with a PIC Microcontroller"[^]. If you choose a microcontroller with a UART then you may easily connect it with the PC.
