The display is 6,9 inch big (150x90 mm) and it's designed to hang it on the wall.
If you print four big and one small piece as I did you can use it as an watch.

If you want to put two displays together you have to glue them together.

ELECTRONICS:

1x Arduino NANO

1x Real Time Clock RTC DS3231

1x Active Buzzer

86x 5mm LED's (color of your choice)

Installation:

You have to print out your variation of displays.
Push the LED's in the holes of the case
Put the cover on the case
Wire the LED's ground from each segment to a different digital output of the Arduino
Wire all the same pieces of the number to the same digital output (e.g. the top LED's of the first segment to the top LED's of the second segment and so on\u2026)
Upload the code to the Arduino and you'r good to go :)

You can download the code in \u201cFiles\u201d or copy it down below:
