Control Home devices using PC

Hello every one .

I am showing you today a small PC_based control circuit that I made , I hope you like it .

Description:
Small electrical circuit that can control any electrical appliances (Lamp , T.V , Fan , .... etc.) from your PC .

Idea:
Using the parallel port of the PC to send a control signal (ON/OFF) to a Relay that's connected to the electrical device you want to control.

Timing functionality is also added by the control program not electronic components. So ,you can switch the device on and off after some duration or at specific time .

The circuit is controlled by a small C# Program
