Is there a specific motor driver that I should use for these: http://www.pololu.com/catalog/product/1123 motors , I'm going to use two with the LM393 dual comparator chip for a line follower. Im going to use two CDS photoresistors for the sensors. Would This: http://www.pololu.com/catalog/product/24http://www.pololu.com/catalog/product/24 work for that? and should i put this in a socket?
-
yes that will work fine. you can put it in a socket if you think something may go wrong in your circuit or you don't trust your soldering.
-
yeah i dont really trust my soldering, im using a comparator chip so should i put the motor driver or comparator chip first?
-
it depends where they're going. if you think you may burn them out rather use a socket.

where they're going, can you clarify, do you mean what other components are hooked up to them?
-
pins 5 and 12 are ground so is that where is solder in the ground leads of the motor? 4 and 13 are the heat sink pins so is that where i wire the heat sink, sorry i dont know that much about heat sinks or pretty much IC's

it sounds like you're trying to build a "herbie", which is a microcontroller less robot that compares signals to go left or right
a basic "herbie" circuit is something like this: http://downloads.solarbotics.net/misc/herbie1.gif
i'd consider looking into it, google "beam herbie" if you want more information.
if you want information about how motor drivers work, look at the SoR H-Bridge tutorial, found here:
http://www.societyofrobots.com/schematics_h-bridgedes.shtml
motor drivers are basically H-bridges, read through that tutorial, it will give you a greater idea of what you need to do

i found a circuit using the same motor driver
