• Arduino Functions:
  — Replaced flux.setPinMode with pinMode
  — Replaced flux.writeDigitalPin with digitalWrite
  — Replaced flux.readDigitalPin with digitalRead
  — Replaced flux.delay with delay
  — Replaced flux.millis with millis
• Non-blocking Timing:
  The code toggles the outputs every 500 ms using the elapsed time from millis(), so the main loop remains free to poll inputs continuously.
• Edge Detection:
  A rising-edge on an input is detected when the current state is HIGH and the previous state was LOW.
