Hello FastLED folks,
Looking for some advice or guidance please on building a 200 pixel, 4 letter WS2811 marquee sign. BTW, I love the information and creativity in this group - a very deep rabbit hole to fall down for sure.
My wife is a huge KISS fan, so as a surprise for her and learning experience for me, I’m working on an LED sign, similar to this gentleman’s work: https://imgur.com/a/n5bFc. The goal would be some simple patterns to start, perhaps getting more complex as I learn more. For example, lighting up from left to right, right to left, etc, lighting each letter at a time, all letters on “fire”, etc.
I have 4x50 strings of lights and a NodeMCU 8266 I was planning on using. I’ve done some searching in this group and it looks like the “RGB Shades” may be a good starting point with the XY mapping, etc. I started a Google Sheets mapping as a draft of what that might look like as a 12x34 matrix (see below).
Questions for the group:
- Is the RGB Shades code a good starting point? Any other basic examples that would be helpful? My level of expertise so far is with various single strips of WS2812s around the house running various patterns such as the demo reel, and TwinkleFOX.
- Should I run all four letters/200 pixels from one data pin? Or one pin per letter?
- Does my draft matrix and layout of the LEDs look ok? (Starting with pixel #1 at the lower left of the “K” and winding around through all letters. The last visible pixel would be #200.)
- If I wanted to do different effects/patterns per letter, would each letter have it’s own XY mapping/array?
- Other advice/pointers?
Thanks in advance!
