SparkFun Ethernet Shield Quickstart Guide

by Jimb0



Overview

In this tutorial, we’ll cover how to get up and running with the SparkFun Ethernet Shield. Requirements, hardware, assembly, and programming will all be covered. Follow along, and your Arduino should be skimming Twitter and hosting webpages in no time!

Requirements:

  • Headers (and soldering tools)
  • An Ethernet cable
  • µSD Card (optional)
  • Arduino Development Board
  • Arduino Software

Hardware

  • The SparkFun Ethernet Shield is comprised of two stand-out components - a Wiznet W5100 TCP/IP embedded Ethernet controller and a µSD socket.

    • The W5100 is a powerful little chip, which implements all sorts of complex network protocols - TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE, and the physcial Ethernet layer. This alleviates a lot of programming stress on us and memory stress on the Arduino. All of the communication between the W5100 and the Arduino is SPI-based and handled using the Ethernet library, which we’ll discuss in the firmware section below.

    • The W5100 is supported by a number of components - capacitors, a crystal, reset monitors - but most especially an Ethernet jack, actually a MagJack. Inside that little RJ-45 jack are a number of transformers and magnetics required for isolating Ethernet signals (you could say this jack is…more than meets the eye). There are even some LEDs poking out the end.

  • The µSD socket extends near the edge of the shield, where the card should be inserted. The socket sits next to a 74HC4050 (high-to-low level shifter), which handles all of the 5V-to-3.3V voltage shifting (those delicate µSD cards shouldn’t be subjected to 5V signals).

  • Some of the less spectacular components (don’t tell them I said that) on the Ethernet Shield include a reset button, 3.3V regulator, and a number of blinky LEDs. The reset button works just like the one the Arduino itself, though it’ll also reset the W5100. The LEDs include a power indicator LED, as well as a number of status LEDs (Ethernet receive/transmit, collision, and speed) tied to the W5100, which will appear to have a mind of their own.

Teleduino

by Teleduino



Overview

Teleduino converts your ethernet enabled Arduino into a powerful and versatile tool for interacting with devices over the internet. Not only that, but it makes it quick and easy.

Teleduino is now available for the Arduino Mega range of boards!

Once your Teleduino is configured, it automatically connects itself to the Teleduino server when powered on. The Teleduino server translates instructions received from the internet into actions on the Teleduino device.

Using the Teleduino platform, you can perform the following tasks with your Arduino via the simple web service:

  • Reset, ping, get uptime, get free memory.
  • Define pin modes, set digital outputs, set analog outputs, read digital inputs, read analog inputs, or read all inputs with a single API call.
  • Define up to 2 ‘banks’ (4 for the Mega) of shift registers. Each ‘bank’ can contain up to 32 cascaded shift registers, giving a total of 512 digital outputs (1024 for the Mega).
  • Shift register outputs can be set, or merged, and expire times can be set on merges (you could set an output(s) high for X number of milliseconds).
  • Define, and read and write from serial port (4 for the Mega).
  • Read and write from EEPROM.
  • Define and position up to 6 servos (48 for the Mega).
  • Interface with I2C (TWI) sensors and devices.
  • Set preset values for the above functions, which get set during boot. Preset values are stored in the first 178 bytes of the EEPROM (413 for the Mega).

Build a cloud-ready temperature sensor with the Arduino Uno and the IBM Watson IoT Platform

Part 2: Write the sketch and connect to the IBM Watson IoT Platform

by Kyle Brown



Overview

In Part 1 of this four-part tutorial series, I discussed the design of a project for monitoring temperatures in my wiring closet, built by using the Arduino Uno and the Virtuabotix DHT11 temperature sensor. I showed the construction of the circuit for the project and walked you through the installation of the Arduino IDE and how to test out each of the individual components of the project with different Arduino sample sketches. You’re now ready to see the design of the sketch that ties the IoT project into the cloud and the steps to enable monitoring of realtime temperature and humidity data remotely. However, first I need to discuss the protocol that you’ll use to communicate with the IBM IoT Foundation: MQTT.

What is MQTT?

MQTT (formerly Message Queueing Telemetry Transport) is a lightweight, fast communications protocol designed for the Internet of Things. It has its origins at IBM (where it was originally developed by Andy Stanford-Clark), and it has since been submitted to Organization for the Advancement of Structured Information Standards (OASIS) for standardization, where the current version of the protocol standard is version 3.1. The MQTT V3.1 Protocol Specification specification states that its purpose is to be a “lightweight broker-based publish/subscribe messaging protocol designed to be open, simple, lightweight and easy to implement.” In the time since its introduction, the “easy to implement” part has certainly proven to be true, as several different libraries implementing MQTT clients have been developed. You can find links to nearly all of them at the Eclipse Paho project page.

MQTT is perfect for use in embedded devices because it:

  • Is asynchronous, with multiple different levels of quality of service, which is important in cases where Internet connections are unreliable.
  • Sends short, tight messages that make it handy for low-bandwidth situations.
  • Doesn’t require much software to implement a client, which makes it great for devices like the Arduino with limited memory.

MQTT is the protocol that the IBM IoT Foundation QuickStart is designed to take input on.

How to wire and test your Arduino + Ethernet Shield

by Zugiduino



Overview

This post show how to wire and connect with Ethernet Shield, And how to test your Arduino board with Ethernet Shield by using a simple web-server example.


In this post, he will focus on how to wire Arduino UNO R3 to Arduino LAN Ethernet Shield R3 and Arduino MEGA R2 to Arduino LAN Ethernet Shield, then test whether it works or not.

Notice that, he will only use Serial Cable, Arduino UNO R3, Arduino MEGA R2, and Arduino LAN Ethernet Shield R3 as the model, because there comes a lot of problem when deals with them, so I hope this guidance will help you. Here, the good idea is we do not need to use any ethernet cable.

Arduino UNO

Here is the wiring from UNO to Ethernet Shield:

Connect ICSP (UNO) to ICSP Header (Eth Shield) with common arrangement.
Then, pin 4 to pin 4 and pin 10 to pin 10. That’s all !

Arduino Mega

Refer to 1st picture.

Wiring them, from ICSP to ICSP header with common pin arrangement, then pin 4 to pin 4 and pin 10 to pin 10, that’s all!
