Hi dreamyfriend,

Your c# program may have 2 buttons.

1. ON
2. OFF

When you click on ON, it will send this information through a serial port to the microcontroller's RX port. The microcontroller will turn ON a triac, this triac will turn ON/OFF the electric bulb.

Or to avoid microcontroller I may use the cd/dvd drive. C# ON button will eject the drive and the tray will hit a microswitch, which would turn ON the bulb. To turn it OFF, I can then download "Eject and Close CD Tray Version 1.0.0.0" a commandline application from Softpedia to open and close cd/dvd drive. Then call this program from C# GUI which contains 2 buttons as mentioned before

1. ON
2. OFF

Ok, hope others may give you better suggestion.

Best regards.
