Arduino Mega
Introduction arduino mega :
The Arduino Mega 2560 Rev3 is a microcontroller board that is based on the ATmega2560 microcontroller. The Arduino boards were widely used in the automation industry and embedded projects. Almost all boards work similarly with few exceptions. Other boards like Arduino Uno, Arduino Nano, Arduino Every, and Arduino Beetle all seem a good pick for projects that require little memory to store the program.
However, when the nature of projects is complex and requires more memory and a rich set of I/O interfaces, the Arduino Mega 2560 Rev3 comes into play. This board was an advanced version of the board Arduino Mega 2560. I suggest you buckle up or read this entire post till the end as I’ll detail the complete Introduction to Arduino Mega 2560 Rev3 covering pinout, pin description, features, programming, or applications. Let’s get started.

Circuit Operation:
The Mega 2560 can be powered via a USB connection or with an external power supply. The power source is selected automatically.
External (non-USB) power supply can come either from an AC-to-DC adapter (wall-wart) or a battery. The adapter could be connected by plugging a two.1 mm center-positive plug into the board's power supply jack. Leads from a battery can be inserted in the GND and Vin pin headers of the POWER supply connector.
The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7-V, however, the 5-V pin may supply less than five volts or the board may become unstable. If using more than 12-V, the voltage regulator may overheat or damage the board. The recommended range is 7 to 12 v.
The power pins are as follows:
Vin. The input voltage to the board when it's using an external power supply source (as opposed to 5 v from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power supply jack, access it through this pin.
5-V. This pin outputs a regulated 5-V from the regulator on the board. The board can be supplied with power either from the DC power supply jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and could damage your board. We don't advise it.

The Arduino MEGA 2560 was designed for projects that require more I or O lines, more sketch memory, and more RAM. With 54 digital I or O pins, 16 analog inputs, and a larger space for your sketch it is the recommended board for 3-D printers or robotics projects.

Frequently Asked Questions
How to program Arduino Mega 2560 using Arduino Uno?
Disconnect the Arduino from your computer. LED positive + to 22 of 2560 chip. LED negative - to GND of 2560 chip. Now connect the Arduino board, open Arduino IDE & open 'Blink' sketch from Files-> Examples-> Basics.
Does Arduino Mega 2560 have Bluetooth?
The Bluno Arduino Mega 2560 BLE Bluetooth 4.0 Microcontroller inherits the numerous ports and the abundant resources of the Mega series and adds Bluetooth 4.0 wireless communication function.
What is the advantage of Arduino Mega 2560?
Arduino boards use SRAM (Static Random-Access Memory). The Mega 2560 has the most SRAM space with 8 kB, which is (4x) more than the Uno, or 3.2x more than the Micro. With more SRAM space, the Arduino has more space to create or manipulate variables when it runs
How fast is Arduino Mega 2560?
The Arduino Mega runs at 16MHz- if it was running at a different frequency you would have to use a different board selection when you upload a sketch, it wouldn't work
What is an Arduino Mega 2560 board?
The Arduino Mega 2560 was a microcontroller board based on the ATmega 2560. It has 54 digital input or output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power supply jack, an ICSP header, and a reset button.
