Get inspired with Arduino MEGA 2560

What is Arduino Mega 2560?

The Mega 2560 is a microcontroller board which is designed for more complex projects like 3D printers and robotics projects. It has

• 54 digital input/output pins — 15 can be used as PWM outputs
• 4 UARTs — referred to as universal asynchronous receiver/transmitter that translates data in asynchronous serial communication format
• a 16 MHz crystal oscillator — used to create an electrical signal with a precise frequency.
• an ICSP header — referred to as in-circuit serial programming that used to programme microcontrollers

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.

Programming

The Mega 2560 board can be programmed with the See the Arduino Software(IDE).
reference and tutorials to get more details.

The Mega 2560 can be powered via a USB connection or with an external power supply. The power source is selected automatically.

The ATmega2560 has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of SRAM and 4 KB of EEPROM (which can be read and written with the EEPROM library).

Input and Output

Each of the 54 digital pins on the Mega can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive 20 mA as a recommended operating condition. In addition, some pins have specialized functions
The Mega 2560 has 16 analogue inputs. By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and analogReference() function.

Communication

The Mega 2560 board has a number of facilities for communicating with a computer, another board, or other microcontrollers. It provides four hardware UARTs for TTL (5V) serial communication. The Mega 2560 also supports TWI and SPI communication.

Automatic Reset

Rather than requiring a physical press of the reset button before an upload, the Mega 2560 is designed in a way that allows it to be reset by software running on a connected computer.
