In the ARDX documentation, I did not find any recommendation about using a separate power supply. That probably means any robotic implementations would have to have multiple power supplies. Can you point out discussion of this particular anomoly so I can avoid it when the time comes, in particular if there are different considerations for setting up the circuit because a separate power supply is used (or necessary).
Would such a recommendation about motors also apply to servos, or possibly anything else that requires use of a transistor in the circuit?
Are there any other types of circuits that have this type of consideration?
Is there anything that can be added to the existing ARDX Circuit #3 layout to compensate for the noise that is generated by running the motor (a power rail feedback filter or some such).
However, attempting to run this arrangement is a failure...UNLESS there is ground continuity from the 2nd breadboard back to the Arduino
Thus, one can power an Arduino through its 5 volt pin as long as that power is regulated.
In a nutshell, powering the motor ciruit through a separate breadboard is not the answer because the feedback from the motor through ground continuity is still an issue. Thus, one might expect that if you use a motor shield, you cannot run other circuits on another breadboard with that same Arduino.
