I bought the DIY BASIC air quality sensor a few month ago and was looking to see how connect a WS2812B LED strip to it. Any guidance would be appreciated.
I haven’t done this myself, but the WS2812b only needs 3 wires. 2 for power and ground, and 1 for data. You would need to select a pin that is unused currently and connect the data wire to it.
Then modify the code to add in LED functions using the pin you selected.
