Hello everybody,
I am New in this forum. I'm French and I built a doodle bot robot. when I send him the test phrase "I AM A ROBOT" with Arduino, he wrote the sentence backwards from right to left. What should I do to him to write well "I AM A ROBOT" and not "TOBOR A MA I" ?
In advance thank you for your reply and sorry for my bad english
The only thing i can think of is…
Try reversing the wires to each motor. if the pins are reversed it would probably wright upside down and backwards because the wheels turn backwards when the controller thinks its turning forward. You where lucky you hooked up both backwards, if only one was backwards it would look like it was going crazy.
Good Luck and let us know how it works.
