This tutorial shows how to build a basic IoT device using an Arduino Uno (R3) board equipped with an Ethernet Shield (W5100). The device is configured both as MQTT publisher (for publishing local ...

There are four socket connections that are supported simultaneously while utilizing W5100 chip. Using long wire-wrap headers, the Ethernet shield can be connected to an Arduino board. Another shield ...

The article is a tutorial on how to control 16 relay through Arduino microcontroller with Ethernet shield W5100.

Arduino have taken the tiny wraps off of the official ethernet shield for their open-source prototyping platform, which adds network connectivity to the device. Based on the Wiznet W5100 ethernet ...

The Arduino averages samples over a 20 second period, calculates power used, and uploads it using an Ethernet Shield. The shield can’t do DNS lookups, so he uses a WRT54G to negotiate with the ...

Arduino UNO SPE Shield adds Single Pair Ethernet (SPE) and RS485 to Arduino UNO and compatible boards, notably the Arduino UNO R4, via a Microchip LAN8651 SPE controller. Single Pair Ethernet relies ...

You can now add WiFi to Arduino for about $3 thanks to ESP8266, and it’s been long possible to add Ethernet with ENC28J60 module now selling for the same $3. Alternatively, if you want some a little ...
