Arduino Mega 2560:
The Arduino Mega 2560 is actually a microcontroller board in light of the ATmega2560 (datasheet). It has 54 digital input/output pins (of which 15 can be utilized as PWM outputs), 16 simple inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything expected to bolster the microcontroller; simply associate it to a PC with a USB link or supply power to it with an AC-to-DC adapter or battery to begin. The Mega has similarity with shields designed for the Arduino Duemilanove or Diecimil. The Mega 2560 is really a redesign to the Arduino Mega, which is replaced by it. The Mega2560 is not the same as all former boards in that it utilizes no FTDI USB-to-serial driver chip. Rather, it includes the ATmega16U2 (ATmega8U2 in the revision 1 & revision 2 boards) customized as a USB-to-serial converter. Here a Schematic Circuit Diagram for Arduino Mega 2560 is shown…

About the company:
Arduino is a software organization, projects & clients’ group that outlines and makes PC open-source hardware, open-source software & microcontroller based packs to manufacture digital gadgets and intelligent articles that can sense and control physical devices.The venture depends on microcontroller board plans, delivered by a few sellers, utilizing different sorts of microcontrollers. These frameworks give sets of digital and simple I/O pins that can be interfaced to different development boards (termed shields) & different circuits. The boards highlight serial communication interfaces, including Universal Serial Bus (USB) on some demonstrates, for stacking programs from PCs. For programming the microcontrollers, the Arduino venture gives a coordinated development environment (IDE) in view of a programming language named Processing, which likewise underpins the languages C and C++.
The primary Arduino was presented in 2005, focused to give minimal effort, simple path for tenderfoots & experts to make gadgets that can interface with their surroundings utilizing sensors and actuators. Usually seen case of such gadgets proposed for fledgling specialists incorporate straightforward robots, indoor regulators, and movement locators and so forth.
Arduino boards are accessible industrially in preassembled structure, or as do-it-without anyone else’s help packs. The hardware plan determinations are straightforwardly accessible, permitting the Arduino boards to be delivered by anybody. Adafruit Industries assessed in mid-2011 that more than 300,000 authority Arduinos had been monetarily created, and in 2013 that 700,000 authority boards were in clients’ grasp.
