I'm playing with a stepper motor but starting to think a servo may be the way to go. So looking for some advice.
I need to rotate a safe dial 4 time anti-clock to a specified number then 3 times clock to another number etc.
Now with the cheapo stepper motor i'm experimenting with after a few times I start to drift and its not very accurate. A safe lock has a theoretical 1,000,000 combinations (Although that can be cut down dramatically to about 400,000 when know how).
So what would be the better approach to a sustained dialling attack like this.
I need to be able to accurately divide 360 degrees into 100 increments 3.6 degress It would also be nice to get feedback when the motor stalls or cant move.
