    Arduino Drawing Robot

    Hi, i've done this little robot, but i've a question about the batteries and how them was connected. They are in a serial configuration, so basically we do a count for establishing the V (1.5 x 6 = 9V)If we put a 9V in our arduino, this will reduce the V to 5, due to a in-built regulator in the pin input VIN of arduino. But how we "feed" all the other stuff?In the picture created with fritizing seems like the stepper are "feed" with 9V which is weird because they need 5V.. can anyone help me?
