Vin: It is defined as the input voltage, which is applied to the Arduino Board when it is using an external power source.Note: This product has been replaced by the newer Arduino Mega 2560 R3.

RX and TX: The successful flow of data is represented by the lighting of the TX and RX LED.

3V3: The 3V3 pin works as the output regulated voltage of 3.3V.5V: The 5V pin works as the output regulated voltage of 5V.The Microcontroller operates with the reference voltage provided by the IOREF. The shields are connected to the Arduino Board. It allows the shields to check the operating voltage (3.3V or 5V) of the board. It stands for Input Output voltage REFerence. The multiple SPI devices in Arduino are able to share the same SS, MOSI, and MISO lines. The MISO, MOSI, and SS support SPI communication. It is the Slave Select line, which is used by the master. The slave line in MOSI is used to send data to its peripherals. The MOSI line Arduino carries the data from Arduino to the control devices of SPI. It stands for Master Output/ Slave Input. The slave line in MISO is used to send data to the master. SPI can even have various devices on the bus. In slave, it works as the input of the clock generator. It is popularly used by the microcontrollers to communicate with one or more peripheral devices quickly.

It stands for Serial Peripheral Interface. The digital pins have the value either HIGH or LOW. The 15 pins from the digital I/O are PWM (Pulse Width Modulation) pins numbered from D2 - D13 and D44 - D46. There are 54 digital Input/Output pins from pin numbered from 0 to 53. It can also act as GPIO (General Purpose Input Output) pins. The function of Analog pins is to read the analog sensor used in the connection. There are total of 16 Analog pins from A0 - A15. The SCL is a clock line, while SDA is a data line. The I2C is a serial communication protocol that uses SCL (Serial Clock) and SDA (Serial Data) to receive and send data between two devices. It is the two-wire serial communication protocol. The structure of the ICSP header is shown below: The program or firmware with the advanced functionalities is received by microcontroller with the help of the ICSP (In-Circuit Serial Programming) header. The adapter is plugged-in to the power jack of the Arduino Mega board. The power jack is used to supply the power to the board. It permits the Arduino to communicate with serial devices. It stands for Universal Asynchronous Receiver and Transmitter. We usually plug the USB cable in the USB port to load the sketch to the board. It is essential for the programming of the Arduino Mega board. It allows the board to connect to the computer. The ground pins are used to ground the circuit. It is recommended for complex projects, such as Robotics, etc. It is used for the boards that require more memory, sketch, and I/O lines. Here, AVR stands for Audio Video Recorder and RISC stands for Reduced Instruction Set Computing. The Mega 2560 is based on AVR RISC Architecture. ATmega2560 Microcontroller - The Atmega2560 is a CMOS (Complementary Metal Oxide Semiconductor) low powered 8-bit microcontroller.The description of pins present on the Arduino board are listed below: The Pinout of Arduino Mega is shown below: The advantage of using the Arduino Mega board over other boards is that it gives the advantage of working with more memory space. The Arduino Mega is based on ATmega2560 Microcontroller.
