Arduino Uno Board

Introduction
The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It 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 a AC-to-DC adapter or battery to get started.
The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip.  Instead, it features the Atmega8U2 programmed as a USB-to-serial converter.
"Uno" means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and  version 1.0 will be the reference versions of Arduino, moving forward. The Uno is the latest in a series  of USB Arduino boards, and the reference model for the Arduino platform.

  • These things are really versatile. The real magic of this doesn't come from the hardware (tbh, the board isnt all that well designed in my opinion), but the IDE and the libraries that come with it. Those goodies transform a regular old atmega328p into this beast image

     

    ...Although I did get fed up with using other people's libraries, so I reverted back to just programming AVRs in C image

    But I now use the Arduino as an ISP programer! DEFINITELY worth the 30 odd dollars I spent on it.
