Clock cycles through chemical elements

The latest addition to the Multi-face GPS Clock is a clock face that for hour, minute, and second cycles through the corresponding chemical element in the periodic table. This is shown in the image to the right.

This is screen number 39 for this clock, all of them selectable by rotating a rotary encoder. The project, with Arduino Mega hardware and software is documented on Github, where the current release is v.1.6.0 (2023-04-14).

The display also shows  the full name for the element corresponding to the second, as shown above for element 3 which is Lithium. It is located in group (column) 1 and period (row) 2.
