How can I figure out indefinitely that a particular stepper won't blow up my chips?
The adafruit motor shield will be feeding 12v into this 10v stepper, so would this create a problem?
Also, can I still use Arduino pins to break-out onto a breadboard even with the motor shield installed? How would one hook a breadboard up to the Arduino with this motor shield?
my stepper motor jitters out (does nothing but jitter).
the FAQ say that the practical current limit is 2amps. Is that for the entire system, or per H-Bridge
what pins will (or will not) be available for me to use?
All 6 analog input pins are available. They can also be used as digital pins (pins #14 thru 19)
Digital pin 2, and 13 are not used.
The following pins are in use only if the DC/Stepper noted is in use:
Digital pin 11: DC Motor #1 / Stepper #1 (activation/speed control)
Digital pin 3: DC Motor #2 / Stepper #1 (activation/speed control)
Digital pin 5: DC Motor #3 / Stepper #2 (activation/speed control)
Digital pin 6: DC Motor #4 / Stepper #2 (activation/speed control)
The following pins are in use if any DC/steppers are used
Digital pin 4, 7, 8 and 12 are used to drive the DC/Stepper motors via the 74HC595 serial-to-parallel latch
The following pins are used only if that particular servo is in use:
Digitals pin 9: Servo #1 control
Digital pin 10: Servo #2 control
And what would happen if I run a DC motor rated for higher voltage (say 12v) with the power of only 7.4v? Will that mean the amp draw of the motor also be lower?
