For my school project I have to build a autonomous obstacle avoiding car, I found this tutorial:
Since I'm not very good with programming codes in Arduino I thought it would be great to follow this tut.
But at this moment I don't have to L298 motor driver they recommend, I don't have such type of motor driver at all!
I got this SBT0811 stepper motor driver board which I don't know if this is a replacement for the L298 and such.
So.. I want to follow the tutorial above but I don't have the L298 nor a motor driver at all. Are there any substitutions for this driver or are their any other tutorials for obstacle avoiding cars without a L298?
Any h-bridge motor driver that meets your requirements for current and voltage will probably be a satisfactory alternative for the L298. Have a look (for example) on the Pololu webstite.
But if you are planning to use a stepper motor don't control it with a simple h-bridge. Use a specialized stepper motor driver. Pololu also has examples of those.
I am also very happy with the DRV8833 but its voltage range is lower than the L298.
Somebody recently mentioned the Texas Instruments LMD18200. It looks like it might be pin compatible with an L298 but it uses Mosfets for the power stages.

...R
I think that's one I've used, its expensive and only goes up to 3A since its not a discete MOSFET bridge
like the VNH series (which many pololu drivers use: Pololu - Brushed DC Motor Drivers)
