Questions about my Arduino Motor Controller

hi guys I have bought an Arduino and the Arduino Motor Shield from adafruit. The tutorial on Ladyada says that I can power a motor which has a capacity up to 36V. So i programmed my arduino to run a motor on M2 and then when I check the voltage supply over there its just 3.17 V. So how do I power a 5V motor. Also the amperage on the pin is only 0.49A whereas Ladyada says that I can power a motor upto 0.6A and 1.2A peak.Is everything correct with my shield. I have also read that I can power it from an external supply-How do I do that? How will it help me?

Thanks in advance.

Arduino Motor Control

I have just purchased a new robot chassis for future projects to be built on. Heres a link...



i am unable to find very much info on the motors in the chassis, but i am wandering what sort of motor controler i will need. all i know is that it uses  2 x 9Vdc motors  that are run of 6AA cells. im using an Arduino as a controller and would like somthing thats relitivly easy to code for.
