Arduino is a very popular and easy to use programmable board for creating your own projects. Consisting of a simple hardware platform and a free source code editor with an easy “one-click compile/upload” feature, it’s designed to be really easy to use without being an expert programmer. Arduino is also the most popular microcontroller board for advanced users and all kinds of more ambitious projects. It’s been used to make robots, home automation gadgets, automotive projects, for sensing and controlling lights, motors, locks and servos, sound and video, interactive objects like animated sculptures, toys and games, radio links and just about anything else you can dream up. It can even be a web server and connect your projects to the Internet. A huge number of example projects (including both hardware designs and software source code) are available to help beginners get started.

Plug-in expansion boards called “shields” add extra functionality, and we also stock a handy range of modules to make it easy for you to incorporate sensors, actuators, sound input and output, and visual feedback into your projects.

The current version of the Arduino hardware reference design is called the “Uno” (or “One” in Italian) and is published by the Arduino team. It provides four basic functional elements:

  • An Atmel “ATmega328P” AVR microcontroller
  • A simple 5V power supply
  • A USB-to-serial converter for loading new programs onto the board
  • I/O headers for connecting sensors, actuators, expansion boards, etc The Freetronics “Eleven” is based on the Uno reference design and is 100% compatible with it, but with a number of design updates and improvements.
  • Prototyping area included so you can add your own parts
  • Gold-plated PCB for maximum robustness
  • Connection markings on both top and bottom
  • D13 LED isolated using a FET to prevent input bias
  • USB socket replaced with smaller mini-USB socket
  • LEDs moved to edge of board for easier visibility when another board is stacked on top

The basic reference design is great for general-purpose projects, but it provides fairly minimal functionality. Its hardware functionality can be expanded in two main ways.

The first method is to use expansion boards called “shields” that can be plugged into the top of the expansion headers. Shields can be complete pre-built boards with all parts already installed for a specific purpose, such as the Freetronics Ethernet Shield that provides LAN connectivity.

Alternatively, blank shields called “Prototyping Shields” provide a matrix of free space for you to add your own parts and assemble your own projects to suit your own design.

If you are just getting started with Arduino, your best option is to start with a general-purpose board such as the Freetronics Eleven plus some prototyping shields to experiment with.

BM7133 Programming Arduino: Getting Started with Sketches

This entry level book explains what an Arduino microcontroller actually is (i.e. a very small stand alone computer), introduces you to the Arduino programming language (called, "C") and then describes the basic configurations of Arduino modules. After this, the book really begins. It then goes into the detail of getting Arduino's to deal with the real world, finishing with a discussion on C++ and more sophisticated applications. • Soft cover, 162 pages. 138 x 215mm

RELAY8 (87) Shield - Relay Driver for 8 relays (12V)

Drive up to 8 relays from your Arduino using just 2 I/O pins with this shield. It communicates with your board using I2C, so you can even stack several shields together to drive 16, 24, or more outputs! Includes back-EMF protection and works with a wide range of relays. Perfect for home automation projects! Maximum output current per channel is 115mA, which is plenty to drive common relays.

ELEVEN (22) Freetronics Eleven (100% Arduino Uno Compatible)

The "Eleven" is just like an Arduino Uno – but better! It is based on the existing Arduino Uno but with improvements and updates for ease of use, cost and getting started, so it's 100% Arduino compatible. Also included in the package are a USB cable, and our Getting Started guide sheet. Quick link to the USB Driver installation process for Windows OS As well as the standard Arduino Uno features found here, the Eleven has the following improvements and updates: Prototyping area For those projects where you don't need the extra size or expense of a shield, the Eleven has its own standard prototyping area taking up a quarter of the board. Great for quick sensor and IC projects. There's extra power pads underneath for neat connections. LEDs visible on the edge Wondered what your Arduino was doing? We've carefully placed a nice blue Power LED, plus colour coded RX, TX and D13 LEDs on the right edge of the board so you can see what's going on. Dual crystals We've provided proper crystals for both the primary MCU and the communications MCU, rather than using a ceramic resonator. Micro-USB Connector No more short circuits of the large USB connector against your shields. Our standard Micro-USB connector is firmly mounted and we've included a cable too. Better still, it allows you to power your Eleven from most cellphone chargers! Overlay guide where you need it When you're soldering your project, it's good to know what you're connecting to! All of our boards and shields have a thorough pinout and guide printed on the bottom as well as the top, so when you're soldering underneath there's no need to flip the board over constantly. Top spec MCU Every Eleven has the top specification ATmega328P Microcontroller. D13 pin works for everything The digital I/O pin 13 functionality has been fixed, the D13 indicator LED no longer loads up this pin when you use it as an input. Mounting holes and power jack We've included a fourth mounting hole in the bottom left, there's no more wobbly board troubles if you're fitting it to a case. Helpful markings for the Power Jack size, polarity and voltage are right there on the board when you need them. Auto-power switching and self-resetting fuse protection are standard. It's all in the same place The power jack, headers and ICSP are all in exactly the same location as Arduino standard boards. The Eleven is perfectly compatible with all Arduino shields, projects and sketches. What's in the box? •Freetronics Eleven board •A Micro-USB cable so you don't need to purchase one separately! •Our Getting Started guide

TS (146) Terminal Shield for Arduino

The Terminal Shield breaks out all the Arduino headers to handy screw terminals, making it really easy to connect external wires without using a soldering iron. Ideal for quick experiments or for robust connections! The center area of the shield is also a huge prototyping area, allowing you to add your own parts to suit your project. A blue "power" LED shows when your Arduino is powered up, and there are also red, green, and blue general-purpose LEDs with current-limiting resistors. The Terminal Shield comes with all the supporting components already fitted as surface-mount parts so you can start using it right away, and we even provide stackable headers to allow you to mount another shield on top. Features •Gold-plated surface: solders easily and very resistant to finger oil, etc. •Large prototyping area with through-plated holes. •Clearly marked GND and 5V rails beside prototyping area. •Blue surface-mount “power on” LED. •2 × 100nF power supply smoothing capacitors pre-fitted as surface-mount parts. •Reset button wired through to the Arduino so you can reset it even with the shield mounted over the top. •3 general-purpose surface-mount LEDs (red, green, blue) with current limiting resistors pre-fitted: drive HIGH to illuminate. •Overlay printed on both the top and the bottom of the board so you don’t have to turn it over to see what you’re soldering onto. •Sexy rounded corners.
