Arduino - Automatic Curtain Puller / Opener

I don't have the code anymore lads sorry.

An assembly that pulls the curtains at morning and night.

It is comprised of an Arduino, a DS3231 timer chip, and a small servo.
A timed interrupt alarm from the chip triggers the servo to spin and pulls the curtain open in the morning.
A second interrupt alarm pulls the curtain closed at night.
These times can be changed via code.

There is also a button to "manually" trigger the servo to spin

The first curtain ring is clipped to the pulley string. It is tricky to get the tension of the pulley string correct so that it doesn't slip.

I dont have the code anymore.
