If you ever want to build a robot (who doesn’t!), you can use the digital output to power a DC motor. The Adafruit link shown above includes a great example for a motor shield. This type of board can contain multiple relay switches that can be individually configured as normally open (NO) or normally closed (NC). A relay shield allows you to bring automation to our home appliances. You can also add a microSD card for storing images and videos. If you want to include a touchscreen, an Arduino board can provide sufficient power for place a small touch screen with decent resolution (240×320 is typical). You can use two I2C pins on the Arduino board, which leaves plenty of pins left over for interfacing with other devices. You can easily add a 16×2 character LCD display with controllable backlighting to your project. You can also use UART to control other devices via MIDI. You can generate an analog signal with a DAC on the shield board, and you can use other components to modulate this signal. Music instrument shield, You can turn your Arduino into different digital instruments. You can turn your Arduino into an MP3 player by adding some speakers, a microSD card, and a headphone jack. You could even clone an open-source GPS module and easily adapt it as an Arduino shield. You can easily add GPS capabilities to an Arduino with a simple chip antenna. You can also build your own shield that provides both capabilities. Arduino has retired the WiFi shield, but similar shields can be found from other suppliers or from tutorial websites. As the name says, this allows your Arduino to connect to the internet through Ethernet or via WiFi. Connecting to the worldĪrduino WiFi or Ethernet shield. Here are a couple interesting shields that might inspire your next design. There are hundreds of Arduino shields on the market these days, and going through each will turn this article into a lecture. Take a look at Adafruit for some good examples. Some shields include an array of plated holes for soldering through-hole components, while others are designed for a very particular application and are not expandable. If you’re buying a premade shield, you’ll find that not all of these modules are extensible. Shields generally communicate using SPI, I 2 C, or serial communication, and some use interrupts or analog inputs. Some Arduino shields are designed to use every pin, while some shields leave open pins. Typical shield form factor for an Arduino Uno An example footprint for an Arduino Uno shield is shown below. Power and ground pins are located on one eight pin header, the analog pins are placed on a six-pin header, and the digital pins are placed on the opposite side with an eight-pin and ten-pin header. Note that this is not generally the case with a custom shield, which is normally fabricated for a specific set of functions.Īrduino shields have the same form factor as that of a standard Arduino board. If you use a through-hole shield, you can add more components to the board or rework it as needed. For a small manufacturing batch, you’ll find that they are cheaper compared to custom PCB. Shields are relatively inexpensive to buy or design. Signals are sent from the GPIO pins or other MCU interface, and multiple shields can be stacked together to form a complex system. The layout of a shield board will be compatible with a basic Arduino board, which means they can be plugged in straight away. Arduino shields provide some important advantages: There are a number of capabilities you can add to an existing Arduino, such as Wi-Fi, Bluetooth, motor control, a camera, or other features. What is Arduino Shield Design?Īrduino shields are small circuit boards that sit on top of existing Arduino boards and contain additional components to boost the capabilities of the system. Here’s what you need to consider in Arduino shield design and how to create a custom shield for your new product. If you’re more adventurous, you can create your own shield board that plugs directly into an Arduino module. If you are lucky, you might be able to find an existing shield that will hold your additional components. The other option is to take all the additional components and make an Arduino shield. You’ll also have to replicate Arduino’s functionality in your custom board, or you’ll have to clone an Arduino board.Īrduino shield design with expandable memory and an LCD display First, you could make a custom board that might be more organized, but will require some time to design. Congratulations! If only a couple of ICs and additional circuitry could be added to your Arduino to make it look like a finished product. You probably have a great idea that you tested using your Arduino, breadboard, and what looks like a bird’s nest of connectors, and it works great. Get Started with Altium Upverter, Sign Up Now.
