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
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?
