sorry for troubling i but i will figure it out :D i wanna make some smaller things to test:)


This is the main problem I have with the Arduino... It encourages people to over-reach their knowledge and ability without offering them any form of training in the basics.

Do you even know Ohm's Law?

That last regulator is the negative voltage equivalent of the 7805 - yet another linear regulator.

Close Amazon.  They're not a good electronics component supplier.

You should be looking at people like Mouser, Digikey, RS, Farnell, etc.


ok thanks:) and does every one go thrue this?

Yes.  At least 2 years worth to get their first degree and more for advanced degrees.  They also pick up spelling, punctuation, and grammar so I guess you can knock off a few months since those topics don't seem to interest you.



Two years of college, followed by 3 years of university, and I'm still lacking in knowledge...

I suggest you spend the $60-odd and invest in a copy of The Art of Electronics - the bible of electronic engineers.  I wish I had the spare cash to buy one.  Failing that, go to your local library and read all you can find on electronics.  Start with the basics - Ohm's Law, etc.  Learn how electronics work.  Then when you understand that you can then move on and build your robot.


I am watching thease tutorials: http://www.youtube.com/watch?v=_LCCGFSMOr4&feature=relmfu


If you just want to build a robot, I suggest you go to a robot forum and look for advice on a starter kit. I'm not being facetious - there are some good robot forums that provide a lot of help for people trying to do what you want to do. You can buy anything from a fully built robot to a partially built robot to a kit of parts to a known good design. Or, if you have sufficient experience and knowledge, you can design the whole thing yourself from scratch if you want.
