Shield Evolution – Flexible Add-ons for Arduino

Shield Evolution

Here at Seeed Studio, we’ve have been working hard to design and build the coolest open source hardware, so that you can create some pretty awesome projects. Arduino shields have been a major focus for us, because of their ability to add some amazing functionality to the easy to use platform of Arduino. But what is an Arduino shield? Briefly, a shield is a board that mounts on top of an Arduino, to give it extended capabilities. They come in all different flavors, from music shields to GPRS shields, with such a wide range available that you can achieve literally anything with them! Who’d have thought you’d ever be able to make phone calls, build touch interfaces, or even control electro-luminescent displays with an Arduino? Arduino shields are the basis for achieving all this, and more!

As an example, here is a demo video of one of our shield collection: the application of EL Shield.

In this article, we’re going to take a look at the awesome Arduino Shield Collection from Seeed Studio. We’ll take a look at some of the interesting shields on offer, and how they can help you build some incredible projects. So, let’s get started!

Usability and Sweet Design

The first thing you’ll notice about the shields is the beautiful boxes they’re packaged in.

This gorgeous design is consistent across the whole range, and really summarizes the kind of effort that we’ve put into designing these shields (believe it or not, they’re also great boxes for storing small components!)

However, it’s when you start using one of our Shields that you really start to appreciate the incredibly user friendly design. Let’s take a look at some examples.

●   Controlling EL (Electro-Luminescent) displays can be difficult, requiring many inverters to power it, and a whole lot of soldering. So we designed a shield to do all of this, the EL Shield. This shield has all the required hardware to regulate and control up to four EL displays very easily. It’s amazing how much easier and less daunting this shield can make EL displays, enabling any beginner to harness the amazing results.

●   Dealing with network communications can be a difficult, if not frustrating task at best. So at Seeed we’ve developed the Wifi Shield that interfaces with the Arduino using only two connections! That’s a major simplification that makes the whole process of network communication a doddle!

●   And what about powering your Arduino. There’s about as many options as there are stars in the sky, so we’ve designed the Energy Shield to safely accept and interface multiple different sources to the Arduino using intelligent power regulation circuitry. This kind of design really expands on the versatility of the Arduino platform, giving you so much more flexibility. The shield can even accommodate charging mobile phone batteries!

We’ve also worked very hard on the physical design of the shields. Each shield now has exactly the same footprint, which guarantees mechanical compatibility. In other words, there’s no need to worry about fitting any combination of the shields in any custom chassis because they all share a standardized design. It’s this kind of design that allows you to focus on your project, rather than getting bogged down by mechanical issues!

Powerful Circuit Design

It’s not just usability and design of our shields that make them a great choice for any Arduino project. It’s also the fact that we’ve spent a lot of time designing the most optimum and efficient circuits. Most of the shields have had improvements made to ensure lower power requirements and less heat dissipation, but let’s take a look at two shields in particular.

 ●  The TFT Touch Shield is a gorgeous shield that provides a full color 2.8 inch touch screen module to be controlled with an Arduino. Previously this required an 8-pin interface, but with a bit of hard work, we’ve managed to shrink this down to 2 pins! With 2 pins you can now completely control a touch screen! It’s obvious what benefits this has, leaving so many pins open for other sensors or actuators.

It’s this kind of effort that really results in some amazing products, and means that you can build some really awesome projects. Let’s have a look at some of the improved critical features of the shields.

ShieldsImproved Critical Features

At Seeed, we believe the only way to create superior shields is to strive to constantly improve them! This kind of iterative design creates the most innovative products, with some of the coolest features and best specs out there. So what kinds of improvements have been made?  Well, here are two examples…

●   The Ethernet Shield is a great addition to any project, allowing you connect your Arduino to a network, but the first version had a limited buffer size and could only support four connections. So, by sourcing superior components, we released an upgraded version featuring a better networking module with double the buffer size for faster data transfer, and the ability to support up to eight simultaneous connections! You’ll certainly appreciate this when you’re looking to build a powerful network enabled device with an Arduino, and even in simpler projects you’ll see the difference!

●   Near field communication (NFC) is an amazing technology, and it’s behind things like wireless payments and e-posters. So we thought we’d design a shield to make the technology more accessible to an Arduino user! The NFC Shield lets you read, write and transmit data via NFC with an Arduino, but our first version used a fixed antenna. Our newest version now has a detachable antenna, so you can place it wherever you like. It also means you don’t need to go through the hassle of putting RFID tags or Cards in a custom enclosure; the shield is completely modular and so easy to use!

Better documentation

It’s no good just providing a set of tools unless the support resources for them are strong. We know this all too well at Seeed Studio, so we’ve upgraded all our online documentation to provide easy-to-follow instructions for all of the shields. We’ve even provided whole sets of sample code for each shield. Let’s look at some examples…

●   We’ve written comprehensive documentation for GPRS shield, guiding you through making your first phone call and sending a text message! This means you’ll be able to use this shield, without having to spend ages looking through cryptic datasheets and command sets!

This kind of effort means that you’re guaranteed to get your shield working, regardless of how experienced you are. And it’s not just the hardware and documentation side of things that we’ve improved upon. We’ve written a whole host of code libraries to completely abstract and simplify so many of the complicated processes that are needed with each shield. Making calls, sending data, reading files, it’s all incredibly easy and achievable with a familiar interface!

We really feel we’ve done something special with our Shield Collection. No longer will there be a need to struggle when trying to achieve astounding things with Arduino. Our set of 17 beautifully designed shields provides a simple and standardized approach for everyone from beginners to veterans, to harnessing some fascinating technologies to use in your projects!
