2025-10-28 (Tu) BonfireLaserTag Countdown timer

The first step in creating the Golden Gun game was to start a one-minute countdown when the tagger received a START command from the administration remote. I thought this task would be the first step in a productive day of programming, but it took all my energy. I had to create several new variables to limit the timer, record its time in seconds, and detect a change, advancing the gameMode integer when the countdown ended. The first time it ran, I saw errant messages on the screen, and I never figured out why they triggered, but when I changed the font size, the problems disappeared. I thought the messages fell off the screen, but they disappeared from the serial monitor too, so I guess that was a quirk of the Arduino IDE. I solved the minor problems and successfully created an animated countdown timer that did not halt any other tagger routines.
