Oooh! Thank you. I have an old account on Project Euler, but I hadn't touched it in a while.

I recently had a breakthrough with my old Parallax Basic Stamp Board (link goes to a newer version with USB), a precursor to the Arduino. I realized I could use its limited language to make interesting things happen in a few lines.

It dawned on me that I grok coding enough now that I can guess a command or type of object, review the specifics of the syntax in the command reference, and get it to run. I'm not planning to be a professional programmer, but I really like getting physical evidence that a hypothesis works.
