HI, im today with a few questions about this project, i got all the mechanics parts, but, the programming its still in blank....
my idea its to use some hall effect sensors, en the "floors" to recognize when a floor its pass, but... this create a big complx in the program, for example, if the elevator its on the 3rd floor, and i want to go to the five(the last), how can arduino recognize in which floor its the elevator???
