I'm making a robotic arm.
having now discovered that hot-glue won't do its coming along fine.
but my current issue is the spring loaded grip is having difficulty staying open-grip (counter-spring) without overheating.
I've burned one SG-90 already .. is there a way to 'lock' the SG-90's position without it having to overheat.
or is there something else that I'm doing wrong.
I don't think the code is relevant because the Servos are not being written to unless the button-controller issues a command to turn a delta-turn value per loop cycle. without pressing any of my control buttons the gripper gets very hot very quickly when it is holding itself open-clawed (against the force of the spring).
is the only solution a better more powerful servo and/or weaker spring. or is there something else I can do?
(earlier problems with sharing a power supply between my voltage-divider button controller and the servos resulting in the servos depleting the power-supply to the button-controller forcing those voltage dividers to work with a lower Vin and getting adverse results has been fixed by connecting the buttons to the Arduino and the servos to an external power supply, so I don't see how this overheating servo could be a power issue)
