Case someone use four motors in car and use for control this motor one Bridge H model L293, we developed one library for that.

Who wants download for test and after reply commenting improvementes, I'll be very gratefull.

My suggestion for improvement would be not to use an L293 in the first place: why would a "Specialist in Industrial Automotation" use something that's what 30? years old when there are so many more efficient solutions available?

I'm a robotics teacher with arduino. In the automated car module we use 1W DC motors, what other suggestion does my friend have to control the motors so simple and fragile?

I daresay Pololu have a suitable one here.

But why do you need a library to use a 293?

The Y outputs follow the A inputs: make eg input 1A high and output 1Y goes high. Write a couple of functions (forward(), reverse(), whatever) in your sketch to make the right pins high and low to get the right motor directions.

You could make the conversion of such functions to a library into a more advance exercise.

In the Brazil, the products POLULO not are easy of buy.

But i agree with you, i will go study e buy the polulu for projects future.
