I have succeed to connect the andruino and the l298p motor together and to linked the motors. So far all was well.

I have downloaded the code from here---> http://www.instructables.com/id/Arduino-Motor-Shield-Tutorial/

I have done the test and everything was ok. But, I did not find the code for the sketch in order to check and control the 2 motors with the joystick.

I want to ask you if you could help me with the code.

I will appreciate it. Thanks in advance!!
