Hello
Arduino nano (Arduino uno will also fits)
4 digit display with tm1637 chip
Ds 3231 RTC

1,5mm electrical wire (decoration)
Glue
When you have printed all the parts, you can place the screen in the "Display" and then you can glue the “DisplayBack” on.
The other parts can easily be slid together.
To put the electronics together, you can follow the diagram below.
Because the screen is bright in the dark, you can set from which hour and up to which hour the brightness should be lower by adjusting the values at the top of the code.
