Where is Arduino defined?

yes, ARDUINO is defined - it's 22 for 0022 (and 0023 I think...) and 100 for 1.0. It's defined by the IDE at compile time (if you do the verbose setting, you'll see g++ ... - DARDUINO=100 ..., which sets that variable)

What is the Arduino used for?

What is Arduino? Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online.

How does an Arduino work?

The Arduino board is connected to a computer via USB, where it connects with the Arduino development environment (IDE). The user writes the Arduino code in the IDE, then uploads it to the microcontroller which executes the code, interacting with inputs and outputs such as sensors, motors, and lights.

What is Arduino Uno board?

The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc. ... The board has 14 digital I/O pins (six capable of PWM output), 6 analog I/O pins, and is programmable with the Arduino IDE (Integrated Development Environment), via a type B USB cable.
