I am a new in steppers, so I have many questions…
First of all - I have made mini pan-tilt system for my webcam with two micro servo sg 90.
It working ok but now I want to change servos to steppers because servos are noisy and I want to make as possible silent pan-tilt.
I have bought two 28BYJ-48 5v + ULN2003 and start to testing…
But now I see that these steppers maybe not suitable for my project - they are very slow.
But I will continue to use it before I decide what other stepper I should buy.
And there is my first quiestion - how can I check the max speed of rotation of this stepper, let’s say, to 90 degree ?
I need to rotate shaft from 0 to 180 or may be more but if it not going round and tear my cables.
What kind of limit should I use ?
And what code for arduino will help me to run this stepper very quickly ?
I have tried many examples but I dont understand it - just copy-paste and compile.
I want to choose one the best way for my task and learn it.
