LED Watch
Saturday, October 03rd, 2015 | Author:

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.


  1. Hour + Minutes
  2. Hour + seconds
  3. 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.
