Major problem

Development Boards Arduino

Hi,

I am trying to build a toy car with an arduino. I am using a tamiya twin motor gear box ( as seen on http://www.pololu.com/catalog/product/1680). This is connected to a track set. ( it pretty much looks like this http://www.pololu.com/picture/view/0J2711). I am using the spark fun motor driver: motor driver 1a dual tb6612FNG on

http://www.sparkfun.com/products/9457.

So i uploaded some code andi took off the track part and i held it up and the wheels moved, but when i put on the track and put it down it would sound like something is movig but it did not. I know that meens that i need more power but what can i do? can i change somethin in the code? Also a side note i hooked up the motor driver to the arduino’s power is that a problem?

In addition i have heard that these motors make a lot of electrical “noise” what should i do about that?

jped,

I suggest you address both the underpower and noise problems by using a separate (from the microcontroller power source) power source for your motor driver board.
