Title: Arduino compatibility with Motor Driver 1A Dual TB6612FNG
Post by: blackheart on March 10, 2009, 02:29:03 PM
Hello! I need to buy a new motor controller for my next robot. And I am not going to wait few weeks again for the arduino/freeduino motor controller! There is a dealer in my country, that sells this motor driver!

My question is: Is it compatible with the arduino? I know it won't fit on the board like a special shield, but I can use a breadboard!

It should be compatible, and I am thinking it is, but I just want to be sure!

P.S. Can you control a DC motor without a motor driver/controller? If you plugged both wires into 5v pins on the arduino, it should work!

That would be dumb, wouldn't it? You can't control speed, or direction?

Yep it should be compatible.

If you plugged the motors directly into the arduino, the microcontroller would blow because the motors would draw too much current. If you plugged both wire of a motor to 5v it wouldn't turn at all, one has to be connected to - and the other has to be connected to +

It will work just fine. I'm actually using it right now for a project.

Can you please post some info on how you control it with an arduino? Just liek any other? Alternating 2 variables? does it need a separate power source?

Some pics would be great!

Also, how would i plug in more than one servo into an arduino without a servo controller?

The arduino has only one 5v power pin from what I know, at least mine does!

Should I get a converter from 9v to 5v?
