Hello everyone,
This is my first topic here and I hope this is in the right topic.
Now, I would like to control my WS2812B leds with my HC-05 bluetooth module.
This is kind of a problem for me since I do not know much about bluetooth, so I am a total noob. I do kind of understand FastLED, but I do not know how to implement bluetooth control in it. When I know how to do that I might know how to make an app to control the leds with, using App Inventor 2.
Can someone take a look at this working spectrum cycle I made for my leds and maybe explain how to implement bluetooth control in it? Can’t seem to find much information about using bluetooth + FastLED, so all the help I can get is very much appreciated!
Thanks in advance!
