Light Seeking Robot - Help

Hey Guys

Just wanting to be pointed in the right direction for a good tutorial on how to create a basic light seeking robot with an H-Bridge, Servo and DC Motor.
I assume that i'll need two LDRs for the sensors so does anyone have any links where it can guide me through the coding as well as the building of the robot? Any help would be appreciated. Thanks.
