Curtains with a bit of an umph _ Stacey Dart

Well after many attempts at making the curtains work, i finally have it… They work!

I have attached some images to help show how the system works.

Had to upgrade to a motor with more torque. As the one given in the kit was not able to turn the pulley with the string for the curtains attached to it

When picking the motor for this project, I had the option of a stepper motor, a motor with a gearbox, or a regular motor that gives out a certain RPM. After buying a regular motor and a geared motor and testing them out, even though the geared motor slowed the curtains down and added a bit of elegance to the system, I decided to go with a regular motor as I liked how dramatic it become with opening and closing the curtains so fast… Although I wasn’t able to show it in this blog, I have added a tune/melody when the curtains open and close just to add a bit of humor to it. All in all I’m quite happy with the outcome. I have learnt a lot about coding, finding parts, time management, planning and most importantly, people are helpful!

Thank you for reading.
