Hello and thanks in advance for your answers!
Please, excuse my English as it is not my mother tongue and I may make some mistakes.
Let me ask you for some help: I am looking for a system like a fan that starts and stops at the very same points. Image a stopped fan that starts spinning. When I swicht off the motor of the fan I want it to stop in the very same place that it started, no matter how many turns it makes. It is ok if the motor still spins (but slower each time) before it "finds" where it has to stopped, this means, once the motor is switched off it can continue spinning as long as it needs until it stops in the desired position.
I think the best way to do it is using stepped motors, but I have no clue. I think that a digital control (PIC, Arduino for example) may do the task.
The arms of the fan will be like 2kg heavy.
What do you think?
Thanks a lot for your interest!
