Ik heb een Adruino Nano en wil een ingang aansluiten en laten zien via een webserver, hoe kan ik dat doen?

Het is me gelukt om via de UIPEthernet.h library de Nano aan te sturen.
Bedankt voor de tip

Nou zit er nog een bug in van de currentLineIsBlank aansturing. Nadat je op een link heb gedrukt de toevoeging bijv: "?relay1off" weer word verwijderd, zodat deze niet continue doorloopt na de volgende refresh. Wat heb ik verkeerd gedaan ?
cpp code

#include <SPI.h>

Dat komt omdat je eerst een boodschap naar de client stuurt en dan pas gaat verwerken. Als je niet wilt dat er iets gebeurt als je niets doet, dan kan je overwegen om tot de verwerking van de relais wachten eerst te bepalen wat je terug wilt sturen naar de client. En dan die client print verder opbouwen. dat doe je tenslotte wel voor de switches
