The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
The Arduino Nano is an open-source breadboard-friendly microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2008. It offers the same connectivity and specs of the Arduino Uno board in a smaller form factor.
Arduino and Arduino-compatible boards use printed circuit expansion boards called shields, which plug into the normally supplied Arduino pin headers. [55] Shields can provide motor controls for 3D printing and other applications, GNSS (satellite navigation), Ethernet, liquid crystal display (LCD), or breadboarding ( prototyping ).
Programmable in C or assembly language using the free CodeWarrior development environment from Freescale, based on Eclipse and in C++ with CodeSourcery. Integrated open-source debugging cable for fast prototyping. The first Arduino Shield Compatible board with two Arduino slots to add more and more shields. BigBrother-USB [277] Freescale MCF51JM128
Total memory of 256 KB. Uses the ATmega16U2 (ATmega8U2 before Rev3) USB chip. Most shields that were designed for the Duemilanove, Diecimila, or Uno will fit, but a few shields will not fit because of interference with the extra pins.

HAVANA (Reuters) -Cuba's national electrical system collapsed early on Wednesday morning after the country's largest power plant failed, the government said, the latest of several such failures as ...
A GPIO pin's state may be exposed to the software developer through one of a number of different interfaces, such as a memory-mapped I/O peripheral, or through dedicated IO port instructions. Some GPIOs have 5 V tolerant inputs: even when the device has a low supply voltage (such as 2 V), the device can accept 5 V without damage.
