i have my arduino turning my canon camera on and off but now i need to figure out a way to power it. the camera fits tightly into a weather proof enclosure - as long as the power supply isn't plugged in! but i could power it via the battery compartment.
the camera takes 4 AA batteries. most likely two sets of two in parallel to double the voltage. (i think that doubles the voltage.) the external power supply outputs 4.3v, 1.5A.
would it be a better idea to feed 3v rather than 4.3v through the batt compartment?
any other advice? i'm just taking a shot in the dark to find a solution to this problem.
