I had attached the screenshot for this

This picture tells you about the Arduino Connection with the with the SHIELD.

EN (Enable Pin) is used to enable and disable the motor drivers. As it is inverted SET this PIN HIGH will Disable the Motors and vice versa.
DIR pinS is used direction of rotation. It highly depends upon your connection, setting this PIN HIGH LOW will make the motor rotation from CLOCKWISE & ANTI CLOCKWISE or vice versa depends upon your hardware connection.
PWM pins are used to control the rotation speed of the MOTOR. Driving PWM signal on this pin will adjust your rotational speed. MAX PWM frequency suggested is 50Hz.
Fault is the INPUT PIN to Arduino with ACTIVE LOW signal indicating some kind of fault is there.

du i have to download and install a library for that shield. – Ronald Fredrick Wollman May 22 at 6:47
No you can use simple digitalWrite and analogWrite instructions for handling all the pins. – Vaibhav May 22 at 6:49
thank you, you have been most helpful. – Ronald Fredrick Wollman May 22 at 7:06
i'v been looking all over for help, i'm surprised there are not tutorials on how to use the Dual Max14870 Motor Driver Shield – Ronald Fredrick Wollman May 22 at 7:07
You can use this l293d with arduino for referral as they have similar properties. They are not exactly same but it will help you understanding with the CODE. – Vaibhav May 22 at 7:11
