Adjustable Digital Table Clock. Temperature and Humidity Meter with 3D Printer and Arduino.

Making a wooden effect table clock box using 3D printer.
Adjustable digital clock structure with Arduino Pro Mini, which can show temperature and humidity.
I used 2 Arduino Pro Mini in the project. I installed the code of the humidity and temperature meter on one. I installed the code of the clock on the other arduino. Because I want to use two oled screens in my project.
Since the displays have the same I2C addresses, it was not possible to work directly on a single card. There are Oled screens that can be replaced, but my screens did not have this feature.
It is possible to use 2 screens with a single card with the I2C multiplexer module. However, this module is not cheaper and not smaller than the Arduino Pro Mini. Using two Arduino was a much more logical and easy solution for me.

Adjustable clock code:

HT22 & 0.91 inc Display CODE: (to be installed on the second Arduino Pro Mini):

NOTE: Before installing this code, the screen resolution in the SSD1306 library must be set for the appropriate option. The .091 inc Oled is 128×32 resolution. The library code should be opened with a text editor and should be made 128×64 passive. 128×32 should be made active. Otherwise, display problems may occur.
