Using shields, anyone can easily integrate key functionalities to their Arduino Uno system with minimal coding and even less handiwork. Some examples of popular Arduino shields include the Wi-Fi Shield, which gives the Uno wireless connectivity, and the Motor Shield, which allows the Uno to control DC and stepper motors. Shields can also be stacked on top of one another to add multiple functionalities to an Arduino Uno.

A shield consists of a printed circuit board that has embedded components and connectors to facilitate its specific capability, and integrated software to communicate its abilities to the Uno. Shields are hardware add-ons that interface directly with the Uno’s pin headers and can expand its capabilities. Because it’s open source, Arduino’s IDE also has an associated, community-driven library, which allows newer users to find frameworks for programs that best suit their needs and lets more experienced coders post their projects and ideas to help introduce those who are unfamiliar with the language to its syntax.Īnother great facet of the Arduino Uno is the Arduino Shields. From a user standpoint, the Arduino IDE contains several useful features to make codes clean and effective, such as text copy/paste and syntax highlighting. The open-source IDE uses Java to create commands and programs. Part of what makes the Arduino Uno so accessible to everyone is the Arduino integrated development environment (IDE). See the chart below to see a detailed mapping of said pins. The Arduino Uno features 20 I/O pins, with the option for six of the digital outputs to function as PWM outputs and six variable pins. The board itself holds a 16 MHz clocking quartz crystal, a USB connector, a power jack, and an ISCP header. With 32 KB of Flash memory, 2 KB of SRAM, and 1 KB of EEPROM, this little processor can carry out most any task you can ask of it. Smaller than the palm of your hand (2.7” x 2.1”), the board is based around the removable Microchip ATmega328P microprocessor, which features 8-bit resolution and its own USB bootloader for reprogramming. The Arduino Uno is one of the most popular compact development boards on the market.
