I was working on the code for the purifier, mainly the UI design and navigation. For now, I manually set data for the air quality, but later I will make it display the actual data from the air sensor. I was able to make the UI have 3 different screens and have the ability to cycle through them using the buttons. Also, using the buttons, you’re able to manually change the fan speed or put it in auto. I still need to work on the auto mode, which will look at the air quality and, based on it, adjust the fan speed. I still need to tighten up the code as It’s a bit glitched, but I think I’ll do it tomorrow
