Thanks for all the advice! I like the idea of the limit switch. I guess, if I want to avoid adding another part to my setup I could manually rotate the motor shaft to a reference position before running the program?
Also, I think the motor may be faulty, as billy joule pointed out. When I use...
Thanks for the answers! I realize I may have phrased my question a bit strangely. What I meant was that I want to detect the angle between some reference point and the arm in the picture. Nidum, is this what you suggest slotted disc and optical switch for?
Hello! I'm completely new to working with arduino and electronics and am currently working on a little project involving a stepper motor. I need to be able to detect in which direction the motor is pointing. In order to do so, I came up with an idea inspired by how potentiometers work. The idea...
Thank you for your response!
I did as you suggested, and quickly realized that there simply are no real solutions. However, in the course I'm attending we are not supposed to use any calculators or graphers, so how would I, without a grapher, realize that these two curves never intersect?
Hello everyone! I'm stuck on a small detail in a math task, and would really appreciate some help!
