I am trying to create a information display using servos and it is VERY important that they are calibrated to the same degree (e.g. if 90-degrees rotation in one servo is the same as 90-degree rotation in the other). I have been using the sg90 and sg92R servos from tower pro and they are not the same, often off by at least 15 degrees. I have changed the wiring to make sure it was a servo issue and not an issue with code - nope: it is the servos. I understand that these hobby servo’s are not known for their…quality…so any suggestion on what to use would be greatly appreciated!
does not need to move anything heavy (basically a piece of paper)
does not need to be fast
just needs to be accurate
