I'm trying to get a home made LED matrix to show a rainbow pattern coming from the bottom up but it's playing this bizarre, dancing pattern. The matrix is in series, with 4X WS2811 addressable LED strips and is 600 LEDs total. 12 horizontal, 51 vertical. The controller is a K1000C that comes with software called LED Edit.

Each strip is powered with a 12v/5A adapter with all grounds going back to the controller. Black wire is ground, red is power and yellow is data.

I realize this deals with software and hardware, but to sum it up I have tried many different wiring setups in the program, but this happens no matter where the data input is unless the pattern is going from left to right. So the rainbow pattern works left to right and vice versa. I should also mention it plays solid colours as well.

My question is, regardless of software or controller issues, did I do something wrong with the wiring? In case it's not easily visible from the photos, the data input is the bottom right corner and the matrix goes in a zig zag pattern following the arrows on the LED strips.

Thanks

  • \$\begingroup\$ it is not possible to answer your question ... one end of each segment needs to be examined, to determine which end is the input end ... then you have to connect input to output \$\endgroup\$

  • \$\begingroup\$ don't forget, you alternated directions of the segments \$\endgroup\$

  • \$\begingroup\$ The bottom right corner is the input...from there it is a zig zag pattern from right to left with each strip continuing power, ground and data from the right to left direction. That is the basic layout for a matrix board based on youtube tutorials I saw. But I am willing to accept if this is incorrect. Does that provide more info? \$\endgroup\$

  • \$\begingroup\$ I thought these were 5V LEDs not 12V.Check V+ drop and use both V+ and gnd return to 5V source for each string with awg24 or UTP wire \$\endgroup\$ Commented Aug 29, 2020 at 13:00

Turns out I had to count the IC chips, not LEDs due to the fact I am working with WS2811 addressable strips. So 51 LEDs vertically needed to be divided by 3 to get 17 chips. Even more confusing, was that horizontally, it was still 12 LEDs in the software. So for 612 LEDs, it was a matrix of 12X17. Then it worked. Hopefully anyone who ends up buying the k1000, T1000, etc and use LED Edit will find this answer if they are running into the same problem. LED Edit desperately needs a manual and needs to add this clarification to the program.
