I have bought 4 of these http://www.sparkfun.com/products/10213 and have been told that they can be used to make an H Bridge that can be controlled by Arduino and used to control a 15 amp motor. Is this possible, and if so how.

Thank you in advance.

have been told

The trick is to be told stuff by someone who knows what they are talking about.

It is normal to have complementary FETs in a H bridge, otherwise you need drivers as well.
16 Amp is a lot of current to be playing about with, it is not a beginners project.
Google "H-bridge schematic" to see lots of different ways to do it, but few have all N-channel FETs.

The below H-bridge link has a schematic you can study.

It was my electronics teacher, but he doesn't know how to build it.

Also would something like this work if I replaced the fets with the fets I was oridginally planning on using.   http://arduino.cc/forum/index.php/topic,53425.0/topicseen.html

Ha, yes. Read through the entire topic. And then read this:

I'm trying to make one as well, I'm just a step or two away from putting it all together.
