Escape Room - Arduino + Ethernet, Webclient - výhra hráča

Úniková hra - Webclient - Arduino

Popis hardvéru:

  • Arduino Nano / Uno / Arduino Mega 2560
  • Ethernet shield Wiznet W5100
  • 5x spínacie tlačidlo
  • LCD displej 16x2 / 20x4
  • I2C prevodník pre LCD displej
  • Elektromagnetické relé SRD-05VDC-SL-C / SSR relé OMRON G3MB-202P
  • Solenoidový zámok dverí 12/24V

    • Popis funkčnosti:

  • Hráč má k dispozícii 5 tlačidiel pre číselný vstup.
  • Štyrmi tlačidlami hráč inkrementuje číslo na každej zo štyroch pozícii.
  • Piatym tlačidlom sú dáta odoslané na webserver, ktorý vráti payload Access / Problem.
  • V prípade "Access" payloadu (odpovede) sa aktivuje relé a solenoidový zámok dverí sa otvorí - hráčom sa umožní pohyb ďalej v hre, indikuje zelená dióda.
  • V prípade payloadu "Problem" ostáva relé v rozpojenom stave, zámok sa neotvorí. Dvere nie je možné otvoriť.
  • Hráč môže byť informovaný o neúspechu aj bzučiakom, alebo LED diódou s indikáciou.
  • Hráč dokáže zadať číslo maximálne 10 krát. Pokusy sa rátajú client-side.

    • Implementácie:

  • Jedno číslo: - tlačidlami 1-5 sa odošle číslo (1,2,3,4,5), pričom jedno z nich je správne. Max. 5 kombinácii, neobsahuje tlačidlo enter.
  • Štyri čísla s opakovaním: - tlačidlami 1-4 sa inkrementuje číslo v rozsahu 0-9 pre každú zo štyroch pozícii s možnosťou opakovania. Max. 10 000 kombinácii.
  • Štyri čísla bez opakovania: - Implementácia bez opakovania čísel (funkčnosť ako pri Štyri čísla s opakovaním), max 5040 kombinácii.

    • Webové rozhranie:

  • Webové rozhranie ponúka možnosť upraviť hľadané číslo v každej z troch implementácii (možno používať súčasne).
  • Zohľadňuje obmedzenie všetkých implementácii (opakovanie, dĺžka číselného kódu).
  • Možno zmeniť prihlasovacie údaje. Možno zapnúť logovanie a štatistiku prijatých dát od mikrokontroléru Arduino. Štatistika úspešnosti hráčov so záznamom prijatých číselných kombinácii, časov prijatia.

    • Schéma zapojenia:
