Arduino Introduction

What is Arduino?​

Arduino is a versatile platform with multiple facets, each serving different roles in the development and deployment of hardware and software for various projects. Below is a breakdown of the different meanings and components associated with Arduino:

1. Arduino Board:​

  • Description: Arduino refers primarily to the physical boards that are used for building digital devices and interactive objects that can sense and control objects in the physical world.
  • Utility: These boards are widely used in prototyping projects in electronics and are favored for their ease of use and open-source nature.
  • Venders: Seeed Studio, Arduino Official.

2. Arduino Software (IDE):​

  • Description: Arduino IDE (Integrated Development Environment) is the software used to write and upload programs to Arduino hardware.
  • Utility: It provides a convenient way to program the boards, simplifying the process of coding and reducing the need for detailed electronics knowledge.
  • Download: Arduino Official.

3. Arduino Toolchain:​

  • Description: When you install the Arduino IDE, it automatically installs a set of tools known as the toolchain. This includes compilers, libraries, and other tools needed to translate the code you write into a format that Arduino boards can execute.
  • Utility: The toolchain simplifies the installation process by automating the setup of compilers and other necessary tools.

4. Arduino Libraries:​

  • Description: These are collections of pre-written code that make it easier to control complex hardware or perform common tasks.
  • Utility: Libraries provide a simple way to interface with hardware, but they can sometimes be inefficient and limit access to hardware features due to their high-level abstraction.
  • GitHub: Seeed Studio, Arduino Official, Adafruit.

5. Arduino Bootloader:​

  • Description: A small program that resides on the Arduino board which allows you to upload new code without the use of an external hardware programmer.
  • Utility: It simplifies the process of uploading new code to the board directly from the Arduino IDE.

6. Arduino Headers:​

  • Description: These refer to the physical configuration of connector pins on the Arduino boards.
  • Utility: They allow for the attachment of various compatible shields (expansion boards) or other devices to extend the functionality of an Arduino board.
  • Arduino Shields: Seeed Studio, Arduino Official.

Programming in Arduino​

  • Language: The primary programming language used in the Arduino IDE is C/C++, though it is often referred to simply as Arduino code or sketches.
  • Sketches: These are Arduino programs that are written in the IDE. They use the Arduino libraries and can be used to control the board's behavior based on the inputs and outputs defined.

Arduino IDE Download​

For every Arduino-supported you might need Arduino IDE to upload the code, for checking whether the board is functioning well and ebabling every application.

How to install an Arduino library​

We have provided a tutorial about how you install an Arduino library. You should notice that almost all of our library was stored at Github. We will provide Arduino libraries when a product need a library, like CAN-BUS Shield V2. But for some other simple products, there is no need to write a library such as Grove - Button.

How to Upload Code​

Here we have another tutorial for uploading the code:

Arduino Cores​

  • Purpose: Arduino cores allow the Arduino IDE to communicate with different types of microcontrollers. They adapt standard Arduino commands to the specifics of the underlying hardware.
  • Examples: Different cores exist for microcontrollers like RP2040, ESP32, ESP8266, and more traditional ones like AVR and SAMD. Some cores are maintained by the community, ensuring support and updates for a wide range of devices.

Arduino-supported Boards​

Seeed Studio XIAO Series consists of 7 versions to satisfy the diverse needs of makers, product designers, and educators. If you're a maker, you can take advantage of its rich community resources to get inspiration and knowledge for your own projects. The XIAO Series offers educators a comprehensive gettingstarted course and detailed wikis to quickly learn how to use XIAO for their projects. If you're a product designer, XIAO SoM User Manual covers everything from Module Selection to Mass Production.
