I built and LED matrix with WS2811 Through Hole leds. My solder job was apparently not the best and there is an error (or multiple) within the matrix. There are 4 leds from each LED. From left to right, Data in, ground, 5v, data out. The matrix is aligned so that the ground leads run to the top and 5v at the bottom. Data lines must be connected so there are wires running from the data out of one row into the next rows data in. I need someone who knows soldering and can replace any dead leds and find any errors in my current wiring. I will supply the current matrix, an arduino that it runs off of and a bag of leds (if any need to be replaced). I am also open to ideas about how to better complete this project the led matrix is curved and attached to a plexiglass panel that i had laser cut. It needs to be see-through and has to be able to flex.
