I am building my first arduino uno project to control a small motor, using the following guide as a reference http://learn.adafruit.com/adafruit-arduino-lesson-13-dc-motors?view=all
It says the following:
The motor that comes with Adafruit Arduino kits does not draw more than 250mA but if you have a different motor, it could easily draw 1000mA, more than a USB port can handle! If you aren't sure of a motor's current draw, power the Arduino from a wall adapter, not just USB.
I have a motor with the following specifications:
Operating voltage 1.5 - 5Vdc.
Rated load 8 g.cm.
Speed@rated load - 13000rpm
Current@rated load - 1A.
No load current - 350mA
What would happen if the motor couldn't draw enough current - would anything break, or would it just not run at maximum speed?
