Arduino (/ ɑːrˈdwiːnoʊ /) is an Italian open-source hardware and software company owned by Qualcomm, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
What is Arduino? The Arduino is one of the most popular and widely used Arduino boards. It's based on the ATmega328P microcontroller and offers a good balance of features, performance, and affordability, making it suitable for a wide range of projects, from simple to moderately complex.
Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board.
Arduino boards have pioneered the concept of open-source microcontroller boards that are affordable, accessible and extensible. They have captured the imagination of enthusiasts, hobbyists and professional engineers alike ever since the original Arduino project started way back in 2005.
Arduino is an open-source electronics platform that allows you to create interactive projects with ease. At its core is a microcontroller, which is essentially a small computer on a single integrated circuit containing a processor, memory, and programmable input/output peripherals.
The Arduino platform is primarily based on 8-bit microcontrollers, such as the ATmega328P, which is used on the Arduino Uno board. However, there are also some official Arduino boards that use 32-bit microcontrollers, such as the Arduino Due and the Arduino Zero.
Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button.
The Arduino is one of the most popular electronics prototyping platforms for learning and using microcontrollers on the market today. This is because the creators of Arduino have simplified the circuitry and programming of the ATMEGA328 microcontroller to the point that anyone can use it.
