Hello. Why is it so strange behaves? Is it all because of the power? I cherish their servo from 5V 3A, but I do not need to manage them all at once. However, when connecting the 15 th servo he twitches, infinitely
From your videos and description of your power supply, I suspect it’s a power issue. We generally recommend using a power supply that can source enough current for the combine stall current of all your servos. If you cannot find the stall current for each of your servos, a good rule of thumb is to budget 1A per servo for standard servos.
