Ogaki adafruit motor pin configuration change and step change.

[raspe827]

The Ogaki shipped with motors from adafruit does not behave as previous model since the gear ratio of the motors and the pin configuration in the motor contact is changed as well.

There are however a quick fix done on this so that the Escornabot behaves as normal or at least close to normal.

A suggestion is that the code should be re written so it would be easy to change the motor configuration from Escornabot.ino
