ARDUINO MICRO BOARD..

 ARDUINO MICRO BOARD..

    The Micro is a microcontroller board based on the ATmega32U4 (datasheet), developed in conjunction with Adafruit. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard.The Micro board is similar to the Arduino Leonardo in that the ATmega32U4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

• What is Arduino Micro used for?

    The Micro appears as a generic keyboard and mouse, and can be programmed to control these input devices using the Keyboard and Mouse classes. The Micro can be programmed with the Arduino software (download). Select "Arduino Micro from the Tools > Board menu. For details, see the reference and tutorials.

Arduino Leonardo

Arduino leonardo board..

        The Arduino Leonardo is a microcontroller board based on the ATmega32u4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button.

• What is the Arduino Leonardo used for?

    The Leonardo board uses a single microcontroller to run your sketches as well as communicate with your PC using USB. This allows Leonardo far more flexibility in its communication with the computer. It also helps to lower the cost of the board.

Arduino Nano board

Arduino Nano board..

    The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.

INTRODUCTION OF ARDUINO LANGUAGE.

 INTRODUCTION OF ARDUINO LANGUAGE.

Arduino uses a variant of the C++ programming language. The code is written in C++ with an addition of special methods and functions. Moreover, when you create a 'sketch' . it is processed and compiled to machine language.

• Arduino programming language.

  The microcontrollers can be programmed using the C and C++ programming languages (Embedded C), using a standard API which is also known as the Arduino Programming Language, inspired by the Processing language and used with a modified version of the Processing IDE.
