Modular Pixel Wall
Description
This is a project I have had in my head for a while and finally decide to claw it out. This is a very simple print that can be made as large as you want based on how much soldering you want to do. Each section is a 4x4 chunk that has a way to align consecutive pieces. There is a second STL that acts as a final "cap" to close off the end. I use CA glue to hold the sections together which worked for me quite well. The LED strips I used are available here: https://www.aliexpress.com/item/2036819167.html?spm Choose WS2812B 5m 30 IP30 For a simple test Arduino Sketch try this, just remove the parenthesis around the pound symbol on the first three lines: (#)include "FastLED.h" (#)define PIN 4 (#)define NUM_LEDS 128 CRGBArray<NUM_LEDS> leds; uint8_t hue[NUM_LEDS]; void setup(){ FastLED.addLeds<NEOPIXEL, PIN>(leds, NUM_LEDS); for(int i = 0; i <NUM_LEDS; i++) { hue[i] = 255 / NUM_LEDS * i; } } void loop() { for (int i = 0; i < NUM_LEDS; i++){ leds[i] = CHSV(hue[i]++, 255, 255); } FastLED.show(); delay(10); }
