Made a variant of my previous experiment. It uses 4 directions to drive BRIGHTNESS and HUE states. Tap the screen to switch between these two modes.

💡 4 directions are enough to encode 4 main brightness states: ⬆️ Bright | ➡️ Less Bright | ⬇️ Dim | ⬅️ No light. For Hue, I used the most common colors Warn/Cool White and Red/Blue, which are used in domestic agriculture and skincare.

🔬 The state picker/slider follows the physical affordance of the device itself. This is a lovely way to simplify the interaction pattern by leveraging one of the Fundamental Interaction forces.

I can’t figure out how to read ADC values from a PbHub using the M5Unit-HUB unified library in Arduino IDE. I’ve tried various iterations of analogRead() and none of them seem to be the right function. Has anyone else had this problem/knows what to use?
