I might make an LED wristwatch. It needs only 11 i/o pins for LEDs and one for a button, though it’s possible to use LED i/o to read a button.
Perhaps USB port for setting and any other features.
Modes:
- Hour + Minutes
- Hour + seconds
- Month + days
Seven segment, binary and bargraph LED watches getting common … so this one uses Roman numerals.
Try the simulation on the sidebar. Click the “crown” checkbox. Obviously javascript must be enabled on your browser.
