- Topic: 2A Dual Motor ControllerYou Reply: I there, I can not test exactly what you ask for but I will do as soon as possible.
By the way I send you a link with the robot working now, everything works well but both motors backward.
Turns are made by: M1->forward, M2->backward and M1->backward, M2->forward.

EDIT: I have tested what you asked for, backward is still not working in any motors but when left/right turn is been made the motor turn forward/backward... Looks like driver does not like backward =( =( - Topic: 2A Dual Motor ControllerYou Reply: I there, I can not test exactly what you ask for but I will do as soon as possible.

I changed pins because my PWM pins are from 13 to 2 but this does not matter.
About batteries, I am using a 2500mha fully charged and as I know them are really powerfull. - Topic: 2A Dual Motor ControllerYou Reply: Hi, I have tested your code without success, goes only forward and when should be going backward stays stopped.

About bee, I will try as soon as possible and will tell you something. But just one question, BT Rx and Tx should be connected to Tx and Rx in Arduino, isn't it? - Topic: 2A Dual Motor ControllerYou Reply: This is the code of motor control:

[*]I am using Mega 2560
[*]Exactly, when I turn left/right one motor gones forward and the other one backward, when I go forward both motors work well but I want to go backward nothing happens.
[*]The H-Bridge is being supplied by 6xAA = 9V separated of Arduino, which is powered by USB, at the moment
[*]The main thing with the Bee is that there are many pins that we don't know where to connect, if we connect power one (3V3, 0V) we can see in the list of devices of Windows/Mobile Phone
[/list]
Thanks. - Topic: 2A Dual Motor ControllerYou Reply: [list type=decimal]
