OK, So what I think I understand:
-
You want motors to be able to act as a "winch" or "Crane", rolling a cable or string up, and rolling it back down again.
totally right i have the knowledge to create that, no problem i did it before.
-
So you need to be able to reverse the motors, right?
Jesssss! an up and down motion.
-
You have some windshield wiper motors but you do not want to use the back-and-forth movement, and you will remove that part??
the motors i have chosen have no back and forth movement in them. They move just in 1 direction all the time, only when i switch the wires it goes the other way.Just like a normal dc motor.
-
You will have to attach some "drum" or "Spool" to wind the cable on.
i already created the spool.
-
You need to know when the weight is at the top, and stop the motor.
yes i think this is able to program?
-
You need to know when the weight is at the bottom, and stop the motor.
right!
More questions:
?? How heavy is the weight the weight is about 1 kg
?? How long do you want it to take to go from bottom to top / not fast, just the top speed of the motor 80 rpm
OK, I see the Video and idea...
- So the weight does not need to stop at the bottom?? No this time it has to stop on his own! that's why i want to use the arduino and not the switch i used in the video.
Details! That's what Engineering is about 
i understand, you give me the questions that are relevant, very helpfull! thanks
