You could get a cheap Android phone or tablet and install MacroDroid or Automate. They allow making simple programs from building blocks. Like “If notification is ckicked display message”. … but there’s the risk this somehow leads to wanting to use the internet/wifi.

Unfortunately Lego Mindstorms have been discontinued AFAIK. It were components to build a robot that could be programmed from a PC. That would have been cool. I think one of the programming softwares was also for Mac. Maybe you can get it second hand?

i already have an idea: dropdown to select the date as a UNIX time stamp in roman numerals

maybe you can do ot like in Jeopardy 😄
