I am just exploring Blynk and it all looks like a fantastic system.
What I don’t see is an app widget for controlling the pixels of a WS2812 strip.
I suspect I could add a button for every pixel but it seems a bit clumsy for a strip of 200 pixels.
I see lot of projects setting colors of the whole WS2812 strip and running animated effects, but I am not interested in doing that, I want to be able to control specific LEDs and set them to specific colors. For example: set pixel 5 to red set pixel 234 to white. (Where the app user can select the pixel numbers and colors.)
Ultimately I want to do things in sets, for example:
set LEDs 3 through 12, 18 24 and 129 to Red
set LEDs 13 through 17 to Green
I understand I can do this in code and allocate LEDs 3 through 12, 18 24 and 129 to say virtual pin 25, then connect a color picker to write to V25. My code would then take that value and set the pixels to the indicated color. I could then add a color picker/button for each set that I defined in the app.
Did I overlook a widget or combination of widgets that would allow arbitrary control of individual pixels?
Thanks in advance,
