Arduino Micro is the smallest board of the family,
easy to integrate it in everyday objects to make theminteractive.
The Micro is based on the ATmega32U4 microcontrollerfeaturing
a built-in USB which makes the Micro recognisable as a mouse orkeyboard.
The Micro is a microcontroller board based on the ATmega32U4(datasheet),
developed in conjunction with Adafruit. It has 20 digitalinput/output pins
(of which 7 can be used as PWM outputs and 12 as analoginputs),
a 16 MHz crystal oscillator, a micro USB connection, an ICSPheader,
and a reset button. It contains everything needed to support themicrocontroller;
simply connect it to a computer with a micro USB cable to getstarted.
It has a form factor that enables it to be easily placed on abreadboard.
The Micro board is similar to the Arduino Leonardo inthat
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 amouse and keyboard,
in addition to a virtual (CDC) serial / COM port.
t also has other implications for the behavior of theboard;
