Arduino with Bipolar Stepper Motor

This demonstration is using an Arduino board, dual H-bridge, 2x NPN transistors and 1x bipolar stepper motor. The circuitry follows this schematic (Bipolar stepper two-wire circuit): http://www.tigoe.net/pcomp/code/category/code/arduinowiring/51

Hey! really cool! I am using arduino too. Would you mind to send me the code to take a look to stepper motors way of working? ;) Nice work!

I'll try to get the code posted somewhere, but I'm afraid its not very much to look at. I simply used the Stepper library included with the Arduino IDE. You can find a really good reference on the Arduino wiki.

I'll update these comments if/when I post the code somewhere. Thanks

Hey, where did you get that motor from?

[mauricetheferret]

I got it from sparkfun electronics online. They are currently sold out but you can place a back order. They also have the spec sheet up available there as well.

@plentyoflife where you able to fine the type of IC to connect to the step motor?

[MrCrazyeyes001]

what size is the motor?



[plentyoflife]

which ic do you use to controll the stepper motor I have an arduino uno card with som nema 17 stepper motors

Hi, the link you've posted with the datasheet is broken! =(

Could you send me it?

Thanks!

so you're driving this motor without outside power?? isnt thsi dangerous haha

i thought its a good practice to use a stepper controller so you can up the voltage for good torque??

@antoine5612 no its not! its surprising

[antoine5612]

@conman33311 I suppose your arduino board burnt out right now....

why so I have to look at your face? egocentric.-
