Arduino mega 2560 pinout code serial#

For serial 0 it includes Tx (1) & Rx (0) for serial 1 it includes Tx (18) & Rx (19) for serial 2 it includes Tx (16) & Rx (17) and in serial 3 it includes Tx (14) & Rx (15). The serial pins of the mega board have four combinations. Where Tx indicates the transfer of data whereas the Rx indicates receiving of data.

Serial Communication-TXDand RXDare the serial pins of board, they are used to transmitting & receiving the serial data.

However, the output voltage through this pin to the board will be automatically set up to 5V. The voltage provided using power jack can be accessed by this VIN pin.

VIN Pin-VIN pin is the input voltage pin of the board, it has range of 7volts to 20 volts.

RST Pin-The REST pin of this Mega board is used to rearrange the board.

GND Pin-The Arduino Mega 2560 board has 5 ground pins from where we can use any pin as required in projects.

The maximum power can be drawn from this board is 50Ma. This regulated power supply gives power to the microcontroller as well as to all the other components used over Arduino Mega board. PIN 3.3V &5V- These are the pins which are used to provide output regulated voltage approximately 5V.Ø Flash Memory : 256kb, 8kb of flash memory is used by boot loader Ø DC Current for each input / output pins : 40mA Ø Digital Input pins : 54 pins (14 PWM output) Ø Input Voltage (recommended) : 7-12 volts The specification of Arduino Mega 2560 are as follows As the Arduino Mega board has more pins, usually it is not utilized for simple general projects, however we can discover more complex project with mega board like temperature sensing, 3D printers, IOT applications, etc. In Arduino Mega 2560 programming can be done using an IDE (Integrated Development Environment is an Arduino software), and it supports C/C++ programming language scripted on JAVA.

The power supply would be given to the board by connecting it to a PC or laptop using USB cables, or can be connected via battery or an AC-DC USB adapter. The board Arduino Mega 2560 mainly includes all possible components which are essential for supporting the microcontroller. It has frequency of 16 MHz, an ICSP header a power jack from where the supply would be given to the board, a USB cable, as well as REST button. Out of all 54 pins we have 16 analog input pins, 4 pins are of hardware port and 14 pins are used as PWM outputs. It includes 54 digital input and out pins.
