Hardwarebeschreibung:

Arduino Nano / Uno / Arduino Mega 2560

Ethernet-Abschirmung Wiznet W5100

5x Umschalttaste

LCD-Anzeige 16x2 / 20x4

I2C-Konverter für LCD-Anzeige

Elektromagnetisches Relais SRD-05VDC-SL-C / SSR-Relais OMRON G3MB-202P

Magnetverschluss 12/24 V

Funktionsbeschreibung:

Der Player verfügt über 5 Zifferneingabetasten.

Mit vier Tasten erhöht der Player die Nummer in jeder der vier Positionen.

Die fünfte Schaltfläche enthält Daten, die an den Webserver gesendet werden und den Nutzlastzugriff / das Nutzlastproblem zurückgeben.

Im Falle einer "Access" -Nutzlast wird das Relais aktiviert und die Magnet-Türverriegelung geöffnet, sodass sich die Spieler im Spiel weiter bewegen können.

Bei Nutzlast "Problem" bleibt das Relais offen, das Schloss öffnet nicht. Die Tür kann nicht geöffnet werden.

Der Player kann auch durch einen Summer oder eine LED mit Anzeige über den Fehler informiert werden.

Implementierungen:

One Number: - Verwenden Sie die Tasten 1-5, um eine Nummer (1,2,3,4,5) zu senden, von denen eine korrekt ist. Max. Die Kombination aus 5 enthält nicht die Eingabetaste.

Vier sich wiederholende Nummern: - Verwenden Sie die Tasten 1-4, um eine Zahl zwischen 0 und 9 für jede der vier sich wiederholenden Positionen zu erhöhen. Max. 10.000 Kombinationen.

Vier Zahlen ohne Wiederholung: - Implementierung ohne Wiederholung von Zahlen (Funktionalität wie bei der Wiederholung von vier Zahlen), Kombination von maximal 5040.

Weboberfläche:

Die Weboberfläche bietet die Möglichkeit, die Suchnummer in jeder der drei Implementierungen zu ändern (kann gleichzeitig verwendet werden).

Berücksichtigt die Einschränkungen aller Implementierungen (Wiederholung, numerische Codelänge).

Anmeldedaten können geändert werden. Es ist möglich, die Protokollierung und Statistik der vom Arduino-Mikrocontroller empfangenen Daten zu aktivieren. Statistik des Spielererfolgs mit Aufzeichnung der erhaltenen Zahlenkombinationen, Akzeptanzzeiten.
