The general idea is to build a curtain opener, using some kind of motor connected to my arduino. Which will cause the pulling-functionality...
So the following options are :
1. DC motor
I feel like this is the least preferable one, since of it's low torque
2. Servo motor
If I "hack" the servo & cut off the potentiometer. I should be able to make it go in to two directions, in 360 degrees and still keep the power of the torque, I think?
3. Stepper motor
This is probably the most recommend one for the functionality I'm trying to achieve but, stepper motors are quite big, maybe a bit too big and quite pricy from what I've seen.
So, to sum it up. I could use a DC-motor, but I don't think it will be able to pull the curtain rope with enough power. I could also use a stepper motor, but it looks too big and heavy for the environment I'm using it in. So, would a "hacked" servo, be an OK solution?
Maybe I'm not seeing other possible problems here that might play a role...
