In this illustration we will going to wire the W5100 Ethernet shield with Arduino UNO, DHTXX Humidity Sensor along with ThingSpeak an AJAX Graphical Representation of the data coming from the Sensor which is connected to our MCU and push
Wiring Ethernet Shield W5100 & Control External Devices with Relay
On this illustration we will going to wire the Ethernet Shield W5100, This shield allows an Arduino Board to connect to the internet. This shield is based on W5100 WIZNET Chip, a network stack capable of both TCP and UDP.
