The
Arduino Uno has 14 digital input/output pins (of which 6 can be used as
PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB
connection, a power jack, an ICSP header, and a reset button. It
contains everything needed to support the microcontroller; simply
connect it to a computer with a USB cable or power it with an AC-to-DC
adapter or battery to get started.The Arduino Uno is a microcontroller
