Hey I just finished soldering my newly acquired motor shield but I have a couple of questions. First of all I would like to power a small DC motor that I bought form the adafruit store (https://www.adafruit.com/products/711). It says the motor works on 6.0V but I have a 12V @ 1A power supply. Would it be fine if I connect this 12V adapter to the power jack on the Arduino Uno board to power the 6V DC motor? Does the chips control the voltage the motor is using? I would also like to know if the two cables in the DC motor have some king of polarity (for example one cable is power and the other ground) or they can be connected either way. Last but not least, when connecting a DC motor to the motor shield, do both cables go into the M1 block for example, or would just one cable go to the M1 block and the other to the ground block? Thank you very much for your help!
P.S. What is the name of the connector this stepper motor has (http://www.adafruit.com/index.php?main_ ... ge&pID=168). I want to buy a cable like this one (http://www.sparkfun.com/products/9922) so I con connect my motor like this (http://www.adafruit.com/index.php?main_ ... age&pID=81) so I don't have to cut the cables from the original connector to connect my motor to the motor shield.

Re: Motor Shield multiple questions
1. it is not suggested to drive a 6VDC motor at 12V, it will die fast
2. we dont know what the connector is, or where to get a matching cable, you should just cut it off

Re: Motor Shield multiple questions
So I'm a little confused here. If I have a 6V DC motor, do I need a 6V power supply to power the motor without doing any damage to it at the same time? What if I have 3 motors that use different voltages (6v, 9v, and 12v) do I use a 12v power supply to power them all? If so wouldnt that 12v power supply damage the 6v motor? Isnt there on the motor shield any kind of voltage regulator? Thank you very much for help!

Re: Motor Shield multiple questions
that is correct, you can only drive one voltage to all the motors. you are better off underdriving than overdriving
the 6V DC motor in the shop can be driven at 9V max so you should use ~9V for all of them.
