Modular RGB LED Sign

Modular sign based on a RGB LED strip controlled by Arduino and encoder.

Hopefully this video will walk you through the build process:

You find the code here:

https://github.com/TheSkjegg/Modular_RGB_LED_Sign

General info:

• NOTE: I did not print all characters myself yet, so if you hit issues please let me know!
• “Smart boxes” shall be used as first character, as it has space for the microcontroller. Encoder is optional, I have made files for both.
• Build rest of the sign of “Regular boxes”.
• Complete the sign by using a “DumbEndAngeled” .
• General inside width of boxes are 30mm, those who differ from this has _XX in the name (like MM_35 and WW_38). Rear covers needs to reflect this.
• I will update with more files and correction as I make them, so make sure you got latest and greatest set of files.
• Code was updated and improved, get the latest and greatest from GitHub
• You find wiring diagram with BOM among the pictures. 

Good luck with the build - I would love to see the result!

Updates:

Update 18.09.24: Added another knob file, as I found encoders with 8mm (6mm flat) shaft. So no need for cutting it.

Update 23.09.24: Minor adjust on rear cover tabs

Update 24.09.24: Added some more symbols

Update 25.09.24: Added numbers and radio symbol

Update 27.09.24: Renamed files for Nordic letters, as names were messed up in zip downloads
