I'm curious as to how much current the Arduino Uno Rev3 is expected to draw when resting at idle as well as when stuck in a small and simple loop. I'm looking to connect the Arduino to a battery source that will be recharged from time to time and so I want to make sure that I'm not causing so much of a draw that it kills the battery before it's next recharge.
So far, my program will cause the Arduino to not really rest (idle state), but rather to monitor the state of a specific pin (using a loop) and not continue to the rest of the program until the pin meets the program's requirements. In other words, from the beginning, my program will leave the Arduino in an endless loop monitoring the pin's condition. Once the condition has been met the program falls through and continues.
Does anyone know what the nominal current draw is with the Arduino on running without a program as well as on but stuck in a loop.
Thanks in advance!
