Hi.

I think i noticed an error in the schematics for the bipolar stepper motor in the Reference part of this website.

I tried following the circuit as described here: http://www.arduino.cc/en/Reference/StepperBipolarCircuit

I did not work so i did some actual thinking and noticed that pin 7 (2in) and 10 (3in) of the L293 need to be connected to +5V with a 10 Kohm resistor.

yes you are right, the posted diagram in the reference section leaves those pins floating, which isn't going to work.
Hopefully the powers that be will repair the diagram.

Thanks for the report and the corrected diagram.  I updated the page.
