The thing is that I would like to power it not with electric current but with battery, this because I do not want to risk that something will happen with the electricity during vacation and I will burn my apartment
So I am considering to create something like this: https://openhomeautomation.net/arduino-battery basically for 2 reasons. First it useless to keep occupied an entire Arduino for just opening a servo motor once, twice per day maximum. Second because it seems that powering Arduino with batteries is not possible, if not for short time.
Now the point is: before proceeding with all this "mess" I would like to understand if it is feasible, but I cannot find anywhere how much is a servo current drain (even without any sort of load). So I cannot understand if, using the servo with batteries will last enough time. And if yes, more or less how much?
What do you think?
