I finally finished Astropass and hit my 11 hours! I cleaned up the whole codebase and got everything running smoothly. I ended up adding custom graphics to the LCD screen like a padlock, checkmark, and warning triangle, and I used a clean switch-case state machine to handle all the terminal transitions without any bugs. I also built in a 3-strike security lockout that triggers an automatic 8-second cooldown if an invalid badge is scanned three times, and I set up a circular log system that prints the full access history straight to the Serial Monitor. Everything is fully pushed to GitHub and ready, so I’m officially moving on to my new Astro-Flora greenhouse project now!
