Cookie dispenser: roles, state and daily reset

fingerprint → whose cookie allowance? admin / child paths need to stay separate
clock resets when unplugged... accidental unlimited-cookie mode. need a power-cycle test

System: Arduino UNO, fingerprint sensor, motor-driven dispensing lever, foam-board storage and chute. Separate administrator enrollment, child enrollment and cookie-withdrawal paths; the daily allowance belongs to a recognized fingerprint, not to an anonymous button press.

Report code: 100 counters, weekday reset and admin enrollment.

Code pointers: the report's Arduino listing uses numOfCookies, now(), weekday(t), newDay, and oldDay. In loop(), a change of weekday triggers a loop clearing 100 cookie counters. This is a software-clock implementation; the conclusion notes that unplugging the device resets its time.

Review questions: What happens to enrollment, counters and clock state after a power cycle? Is a calendar day the intended rule, or a rolling 24-hour interval? The report proposes a time module as a future improvement; it does not establish persistent daily-limit enforcement across resets.
