i want to add an Standard LED-Stripe to my Project. Something like this (german, but ideal for me): http://www.ebay.de/itm/LED-Modul-BLAU-vergossen-3-LEDs-12V-DC-Spot-Strip-BLUE-/150642552824?pt=DE_Haus_Garten_Lampen_Licht_Leuchten&hash=item2312feeff8
Now, these Stripes are Supplied with 12V DC. So how can I make these things glow with my Arduino? Or what additions do I need?
Thank you and Have a nice Day TK
