To run motor i chose this scheme from youtube tutorial http://aksoapy29.comoj.com/diagram2.png
Well i have few problems, i tried this scheme without arduino, using 2 batteries that output 3V. 3V on transistors base and 3v on motor(as it is in the picture). I thought that maybe i should use higher voltage on motor, i bought 9V battery. Before i tried connecting my 3v battery directly to motor and motor worked, now i tried connecting 9V battery to the motor and it does not work.... Can u explain why it is that way? Why transistor may not work and is this scheme adequate at all? That video is here: http://www.youtube.com/watch?v=hcpqt-BREqI&feature=related
I would be really thankful for fast replys as it is my bachelors work and i am a bit low on time. Yes i know since i study in university i should know more, i forgot a lot of things that we learned since never practiced them, but well it comes back slowly:D

DC Motor speed control

Hi guys!
I am creating musical fountain with arduino duemilonove. I want to drive DC motor with arduino, only thing i need to control is speed.
The motor i am using is here http://www.mabuchi-motor.co.jp/cgi-bin/catalog/e_catalog.cgi?CAT_ID=rs_360sh
