im trying to use this stepper motor to put a chicken door up and down and want to know how much power it uses to get an appropriately sized battery and solar panel for it but my voltmeter is broken and haven't been able to fix it, so i figured i could try to guess how many amps it uses and use that to get the battery roughly correct hopefully instead.
i just randomly searched the internet for the specs and found these. i wanted the 5v version but accidentally got the 12v version and it's run through a 5v output on arduino uno annd still works. it has a resistance of 200ohm which i think makes the current (V/R) = 0.025amp but im not sure how many amps that uses in total or is that just for one rotation or its resting state? apparently the resting power use is quite greedy. It would only turn maybe 20-25 times twice a day to put the door up and down but im not sure how to guess the rest.
