Uma das vantagens do Arduino é a possibilidade de comprar ou mesmo desenvolver placas “Upgrade” chamadas Shields. Estas são apenas um plugin para o Arduino, encaixam nos headers e fazem aquilo para que são destinadas.

Deixo aqui uma lista das shields mais utilizadas com o Arduino.

Esta lista é retirada do blog da Makezine.

Ethernet shield – Get your Arduino on the internet
Add Ethernet! Want your Arduino to check email? How about sending a twitter (which can then be easily forwarded to a phone via SMS)? Or grabbing data from a website? There are so many possibilities for projects that connect to the Internet to get data, now there’s an easy way to do it with an Arduino. This shield kit allows you to add and use an XPort or XPort direct(+) Ethernet module (not included) using any 4 pins. All of the TCP/IP stack awfulness is done for you in the module so its super easy to just connect to any server.

Features:

• Shield allows use of XPort, XPort Direct or XPort Direct+
• 3.3V 250mA power supply on-board for powering the XPort
• Arduino reset button and 6-pin ISP header brought up top for fast & easy development

Danger Shield – The only danger is to boredom!
The Danger Shield is an add-on for the Arduino micro controller board. It contains a variety of fun and useful electronic circuits that you can use to do fun and useful things. It is a fully self-contained shield. You plug it into your Arduino, and you can immediately start using it. No extra things to hook up, no external components. Just a really rad board ready to rock. Soldering required.

Features:

• 3x Linear sliders w/ integrated LEDs (independently hooked up to PWM)
• 3x Pushbuttons
• 2x Indicator LEDs (each with a PWM)
• 1x Piezo buzzer (for making noise!)
• 1x Temperature sensor
• 1x Light sensor
• 1x Knock sensor
• 1x 7 segment LED (with shift register)
• Power LED and reset button

Motor Shield – Get your project moving!
A great kit for a full-featured motor shield that will be able to power many simple to medium-complexity projects for your Arduino. Kit comes with all parts necessary, unassembled. Motors and Arduino are not included.

Features:

• 2 connections for 5V ‘hobby’ servos with high-resolution dedicated timer – no jitter!
• 4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 36VDC.
• Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
• Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.Pull down resistors keep motors disabled during power-up
• Big terminal block connectors to easily hook up wires (10-22AWG) and power
• Arduino reset button brought up top (Diecimila only)
• 2-pin terminal block and jumper to connect external power, for seperate logic/motor supplies
• Tested compatible with Diecimila (NG is next!)
• Download the easy-to-use Arduino software library, check out the examples and you’re ready to go!

WaveShield – Add sound and music to your projects!
Adding quality audio to an electronic project is surprisingly difficult. Here is a shield for Arduinos that solves this problem. It can play up to 22KHz, 12bit uncompressed audio files of any length. A great low cost easy-to-make kit.

Features:

• Can play any uncompressed 22KHz, 16bit, mono Wave (.wav) files of any size. While it isnt CD quality, it is certainly good enough to play music, have spoken word, or audio effects
• Output is mono, into L and R channels, standard 3.5mm headphone jack and a connection for a speaker that is switched on when the headphones are unplugged
• Files are read off of FAT16 formatted SD/MMC card
• Included library makes playing audio easy

Xbee adapter kit – Add wireless to your projects!
This adapter board is designed to make adding wireless point-to-point or mesh networking easy. Adafruit looked at all the XBee adapter boards available and decided to design something better.

Features:

• Onboard 3.3V regulator to cleanly power your XBee, up to 250mA
• Level shifting circuitry means that its trivial to connect it to 5V circuitry such as an Arduino without risk of damage
• Two LEDs, one for activity (RSSI), the other for power (Associate)
• 10-pin 2mm sockets included to protect the modem and allow easy swapping, upgrading or recycling
• All the commonly used pins are brought out along the edge, making it easy to breadboard or wire up
• Specifically created for use with an FTDI cable to connect to a computer via USB. This means that you can use or upgrade the adapter with a computer simply by plugging in a cable
• For use with any XBee/Pro pin-compatible module

GPS Shield and data logger kit
GPS shield for Arduino kit with data-logging capability. After building this easy kit, you can create your own geo-locative project.

Features:

• This shield is designed to make GPS projects straight-forward and easy. Plug in a supported GPS module and run any of the example Arduino sketches for parsing GPS data (NMEA sentences), logging to a FAT16-formatted SD flash memory card and storing analog sensor data along with precise location, date and time in CSV format.
• The shield is designed specifically for use with the EM-406a module: the small surface-mount GPS connector is pre-soldered for you. (It is a high-quality engine with quick time-to-fix and excellent reception, even in downtown New York City!) It can also be used with a Tyco A1035D, EB-85A or Lassen IQ module. GPS module, Arduino, and SD memory card are not included.
• The examples work fine on ATmega168-based Arduino (or compatible). Run-time is approximately 3 hours with a 9V battery and up to 12 hours using a MintyBoost, assuming no power-saving features are enabled.

Pocket Piano – Make an Arduino pocket synth
This is a board for making the Arduino into a portable stand alone music synthesizer. It plugs directly into the Arduino board and provides 25 multiplexed keys (2 full octaves), 4 pots, status LED, reset switch, digital to analog converter IC, and a RCA audio jack. The Arduino board with its powerful AVR processor is more than adequate for a wide range of sound synthesis techniques. We have experimented with simple additive / wave-table synthesis, frequency modulation, ring modulation, sampling, polyphony, various arpeggiators. The whole thing can be powered over the Arduino’s USB port for convenient experimenting. Arduino not included. The board is designed to mount easily to 1/8″ panel material, and 1/2″ round keys can be made out of wood or plastic.

Features:

• 25 keys and multiplexer circuitry
• 4 potentiometers, 1 controls output level
• Microchip MCP4921 12 bit SPI DAC
• Passive low pass output filter

Open heart kit – Open your heart!
The Open Heart is an LED matrix of individually addressable LEDs. It can be used to create a brooch or bag light with highly customizable animations. It can be configured so that you can temporarily attach it to fabrics with headers that you simply push through, or you can configure it to be sewn into a project using conductive fabric for a more permanent setup. You’ll need an Arduino to complete this project as well as a soldering iron and basic hand tools.

Features:

• Heart PCB
• 27 Red LEDs
• 6 Resistors
• Right angle headers
• Crimp housings with metal crimps
  6 wire cable

Sanguino Breakout Shield
This is a kit of the Sanguino Breakout Shield board. It is primarily intended as a shield for existing Sanguino boards, but we’ve also included the footprint for a full Sanguino on the PCB as well. Its up to you as the builder to decide what shape the board should take: You can build it as a single board with an integrated Sanguino, or you can add headers that allow you to plug an existing Sanguino into the board. its your choice!
