Hello,
I'm quite new to all this, so it's possible that this question is rediculous.
I'd like to make a RGB led strip respond to music like on this video. This video is built up according to this schematic.
So it uses IRF-520 mosfets.
Now my question is: Can I use L293d motor drivers instead of these mosfets to controll the LED strip colours?
I'd use this scematic: IMAGE OF MY SCHEMATIC.
Do you guys think that would work? I don't have any of these mosfets, but I do have 2 L293d's lying around. And I ask it first because I don't want to break anything 
I do know that I will only have to let the current flow in one direction. So it is indeed quite stupid to use a H-bridge for an application like this one. But I don't know how I should controll a 12V ledstrip on another way using my Arduino (except for the MOSFETs).
Thanks a lot for your help in advance!!
Bram
P.S.: If you draw your schematics in a specialized program for that, it would be nice if you'd give the name of that. You probably already noticed that my Paint-skills are not that high... 8)
Sure, but you will turn them into an I driver, since you will never need to reverse the polarity to the LED's - the whole reason to use an H Bridge.
You would have issues the L293D loses many volts - perhaps you'd have to use
a 15V supply. Definitely much simpler and more satisfactory to use a MOSFET to
control a 12V strip of LEDs
