The thing is, if You choose not to follow tutorial to letter, that means that You have to have enough knowledge on how to achieve goal with changes in mind. For this change Google AVR Timer Tutorial, as it's the way motor is driven. Also, if You search this forum for H-bridge, You'd most likely find How to drive pMOS and nMOS H-bridge? thread.
Good luck :)

What would the H-bridge plug into? Sorry, just starting out in the robot stuff. Trying to read as much info as possible lol :)

Read the articles and tutorials in the "Robot Tutorials (click on this in the top, right corner of this screen.
An H-bridge goes between the controller (typically a micro-controller or processor) and a DC brushed motor.

Hey in the tutorial it doesn't say anything about what kind of wire to use. Does anyone know what gauge to use?
jwatte:
That depends on how high current you want to draw, and how long a cable run you want to run.
I find that 24 gauge twisted/stranded wire can easily supply a 5A motor over short distances. 16 gauge twisted/stranded wire is still very flexible, and is good for things like power busses and main battery connections.
There's a pretty standard function for "safe" currents for "permanent" installations at "industrial" spec, which you can find (for example) here: http://wiki.xtronics.com/index.php/Wire-Gauge_Ampacity
Note that my recommendations push harder than this table recommends, but for battery powered hobby robots with short cable runs (< 1 ft each, say) that's not likely to be any kind of problem.

Thanks for the help guys BUT I have one more question (last one I promise!) I'm going to be using a solderless breadboard, is there anything different i need to do in making the circuit? Or are there some kind of instructions I can follow? Thank you all again for the help!!! :)
