A 1.3-inch OLED on an ESP32-C3 makes a very good bedside clock. It is dim, silent, and impossible to scroll.
The first version refreshed too often and made the display shimmer. Updating once a minute is enough unless a button is pressed.
To do
- Print a simple case.
- Add a physical dimmer switch.
- Make the USB cable leave from the back, not the side.
