While not quite Arduino, I have an ESP32 (Arduino IDE) project to pull tide data via API and show it on a HUB75 led matrix. I've got most of the parts working separately but not quite got them all together yet. What is everyone else doing?
-an LED clock
-dsp learning with a Nicla Vision (i want to learn how to implement digital filters and use them on the signal sampled from the on-board mic)
-a custom keypad for special characters
-a tool to use at work to check encoders signals
