Sensors & hardware which I'll use

Okay I have now to make the choice of sensors et hardware which I'll use on my experimentation.

-Speakers / To use sounds on internet.
-Fan / To allow users to blow on me.
-ElectroKit / To receive electro impulsions.
-Video Projector / To allow users to project movies on my room.
-WebCam / with WebcamFirst to send a movie on the website.
-Light Sensor / to have a better influence of intensity of light of my room.
