Simple PICAXE Servo question
July 11, 2011
I just got my PICAXE dev board and have been enjoying the learning process. Thanks for al the informative posts that I have been able to read.
I'm toying with one of those little blue sg90 servos. I know the min and max positon values are supposed to be 75 and 225 per the PICAXE manual. However, my servo feels like to is fighting a hard stop when swung to position 75. The hard stop seems to be at about 85 or so.
My queston: If I order, say, five little blue sg90s will they all have the same hard stop values? What is the best way to deterime the hard stop values without wrecking the servo?
I know it is simple to limit to position value once the hard stop is understood (if b1 < 85 then b1 = 85), but finding the hard stop points is what I am after.
