Hey everyone. I have been working with addressable leds for a few months now and I thank everyone for their input and advice on various topics I have brought up. So now I am planning on diving into matrix designs and applications and I am not sure where to start. (So far I have only been dealing with strips.) The wiring and electronic end of it I am solid with, it’s the coding that I am still new at. Can anyone suggest a example that I can start with?
If you type “matrix” into the search box to the left near the community avatar, you will have a plethora of examples and previous topics regarding a matrix. Happy hunting…
It is difficult to add anything more than what @Jon_Burroughs suggested given the very general nature of your support request.
You say… I am not sure where to start.
Do you actually want to build your own matrix or do you just plan to get one of the many available off-the-shelf models and start from there?
You need to give us a lot more detail about the microcontroller hardware you have or plan to have, the type and size of array you have or plan to have… etc… etc…
There are also a few matrix example sketches that come with the FastLED library itself.
Well, I was going to build my own out if a excess of APA104 strips that I have, but I think I am going to start with a pre-made 16x16 WS2812B matrix. I am hoping that a arduino uno will run this without issues. Ultimately I am hoping to have a display that can be controlled via a pot or two and a button to switch between different effects. @Jon_Burroughs has a video on YouTube it’s the neopixel matrix with a teensy. That’s my final goal.
@Evan_Bruno Yes a UNO will run a 16X16 array of ws2812b. You should be able to get nice, simple animations going with it.
If you do not have that UNO on hand, maybe jump straight to the Teensy for more performance.
