I am working on a project to run an RGB strip around a large room and have the colour change driven by an Arduino Uno. I have encountered a number of issues and am looking for clarification.
The first strip I used was a 12V strip at 1A/m. This would work fine except the power requirement is slightly ridiculous and it seems I need to put my array of MOSFETs in at every power injection point.
This was when I decided to experiment with a 5V addressable strip to do it. Working with a 5V system gave me more ease as the power requirements are lower and the parts list is also minimal, but after some research, it seems that the signal line will degrade significantly on that many WS2812B's / line length.
I suppose I could but a transistor inline every n-number of 5m strips (similar to the power injectors), however I would like to ask for some opinions from the community around other issues I may encounter, and whether or not this is the right solution for the job.
The scope of the project is to hold a colour for a number of seconds then switch colour based on a predefined program. This program is defined on an external device that uses the Arduino's serial port to communicate the desired colour. The implementation itself is very simple.
The main issues I can see are the power requirements (I think I have this sorted for the 5V version but not the 12V version) and getting the signal to the final LED. On a 60 LED/m strip this could be in the order of around 6000 LED's and that seems like a lot.
What are your views/recommendations?
