Assuming we wish to control a small toy car with an arduino - meaning spinning the right and left wheels forward and backward and being able to break and control the speed, where each wheel has it's own engine (but of course two engines on the same side will run on the same speed and direction).
We saw we have two main options - Buying and wiring up a H-Bridge or buying a motor shield (which is based on one).
Are there any advantages for using a motor shield?
Thanks in advance.
