Trying to get the motor shield working

by boubele on Tue Aug 19, 2008 9:10 pm

Hi all,

i am trying to use the motor shield and I have a few questions.

I use http://www.sparkfun.com/commerce/produc ... ts_id=8420 and I got that running with the stepper tutorial from http://ladyada.net/make/mshield/use.html :

* Step Angle (degrees) :1.8
* 2 Phase
* Rated Voltage : 15.4V
* Rated Current : 0.28A
* Holding Torque : 2.4kg*cm
* Detent Torque : 120g*cm


Right now I have the Arduino connected to external power i.e. a 9V battery.

Quick questions:

1) Ideally what battery should I be using ? I eventually want to rotate a camera using this motor.
2) What is the jumper on the motor shield for ? Does it mean the motor will be powered by the arduino, by the arduino external source, by an external source connected to M+ and GND ?
3) What does the LED mean ?
4) What should that external source be ?
5) Have you guys used this motor before and how would I physically connect it to a plate so that I can use it to rotate stuff ? Is this the right motor for this application ?

Thanks in advance !

as mentioned I did get the stepper motor working from the example in your tutorial page. I believe my questions are not really covered in the tutorial or at least not holistically.

I havent used that motor so all information about driving stepper motors and powering motors is in the user page
good luck!
