The room employing this particular device is un-ish-viewable during the day light tho highly visible at night with interior lights, alight. Due to these parameters, the curtains automatically (photoresistor) open-close relative. Amended is a wifi (lower-case) channel to permit a voice activated command (url submit) to open-close the curtains, shd the moment arise, mmm-hmm.

Notation(s)
1. Timing is every thing .. preferring servos as opposed to steppers, this code requires a precise timing-per-rotation for the width of the curtain draw.
2. Patience .. just bcz it runs at 16mhz doesn't mean you shd. Averaging sensor reads .. delays .. give 'er a rest other wise the curtains will be flappin' back and forth like a chicken raised by geese tryin' to head south.

A friend of a friend who is a friend thru that friend, same friend, third friend over .. has a roommate who steals shaving cream and soap. Using what minor skills made available to me, like angst​, we (me) quickly assembled a very alarming retort.


Up to date -ded​
The culprit was caught .. tho immediately unlikely excuses were levied.
The experience did then highlight some changes one might make - such as - a power diminutive MCU for a timer, denoting and when and how long the device was active - and - a wider toggle lever (printed add-on) to reduce accidental wobble activation.

A wish list would include a wifi-module (power?!) for signaling the event and a diminutive camera to document such thievery. An even more ideal scenario - had time been permitted - a faux can with removed intestines permitting the entire cache of parts to be housed with in.
