What is Arduino?

Arduino is an open-source, programmable circuit board that supports every hardware and software efficiently. Arduino takes input in the form of light on a sensor, finger on the button, any message, and then turns it into an output, such as activating a motor, turning on the light, or publishing something online. You provide necessary instructions to the microcontroller available on the board using Arduino programming language, and Arduino software (IDE).

Arduino has been the brain that works behind thousands of projects and is capable of handling from small to complex scientific instruments. It has a wide and active community of various students, artists, hobbyists that gathered together to contribute to the Arduino platform with incredible information that will help upcoming users.

Ivrea Interaction Design Institute has launched the Arduino as a tool for fast prototyping that helps students. Now, you can use Arduino for a simple project for IoT applications, 3D printing, and embedded environments.

Why Use Arduino?

Arduino is preferred over other boards due to its accessible user experience. Till now, Arduino has been used in thousands of projects and applications. Whether you are a beginner or experienced IT professional (embedded system engineer), you can easily work and get along with Arduino due to its flexibility

It allows you to create low-cost scientific instruments and several embedded system designers and architects for building interactive prototypes. Also,  many musicians make use of Arduino for experimenting with new musical instruments. Some users use Arduino for learning new things like robotics and machine learning.
