ARDUINO MEGA 2560 SERIAL PORT PINS PC

Every analog pin is accessible with the 10-bit resolution which can gauge from GND to 5 volts. It is very important to know that all the analog pins on this board can be utilized like digital I/O pins. There are 16-analog pins included on the board which is marked as A0-A15. The term AREF stands for Analog Reference Voltage which is a reference voltage for analog inputs

This will give you to modify the programming skills in real time. This LED can be operated based on the high and low values of the pin.

This Arduino board includes a LED and that is allied to pin-13 which is named as digital pin 13. Providing LOW value, rising or falling edge or changing the value to the interrupt pins. These pins produce interrupts by a number of ways i.e. The external interrupts can be formed by using 6-pins like interrupt 0(0), interrupt 1(3), interrupt 2(21), interrupt 3(20), interrupt 4(19), interrupt 5(18). For serial 0, it includes Tx (1) and Rx (0), for serial 1, it includes Tx(18) & Rx(19), for serial 2 it includes Tx(16) & Rx(17), and finally for serial 3, it includes Tx(14) & Rx(15). The serial pins of this board have four combinations. Tx indicates the transmission of information whereas the RX indicates receive data. The serial pins of this board like TXD and RXD are used to transmit & receive the serial data. However, the output voltage through this pin to the board will be automatically set up to 5V. The voltage provided by the power jack can be accessed through this pin. The range of supplied input voltage to the board ranges from 7volts to 20volts. When we compare with other types of Arduino boards, these boards are physically superior. These boards offer flexible work memory space is the more & processing power that permits to work with different types of sensors without delay. By using this board, the Arduino mega projected can be designed. All analog pins of this board can be used as digital I/O pins. Every pin of this board comes by a particular function which is allied with it. The pin configuration of this Arduino mega 2560 board is shown below. The USB host chip used in this is MAX3421E.The electrically erasable programmable read-only memory (EEPROM) is 4 KB.The static random access memory (SRAM) is 8 KB.Flash Memory like 256 KB where 8 KB of flash memory is used with the help of bootloader.DC Current for each input/output pin is 40 mA.The digital input/output pins are 54 where 15 of these pins will supply PWM o/p.The input voltage will range from 6volts to 20volts.

The recommended Input Voltage will range from 7volts to 12volts.

The operating voltage of this microcontroller is 5volts.

The specifications of Arduino Mega include the following. These boards work with every existing shield although can adjust to latest shields which utilize these extra pins. Another pin is not associated & it is kept for upcoming purposes. One pin is the IOREF that permit the shields to adjust the voltage offered from the Arduino board. Additionally, there are two latest pins located near the RST pin. The SCL & SDA pins of Mega 2560 R3 board connects to beside the AREF pin. This board can be protected from the unexpected electrical discharge by placing a base plate.

So, the power supply of this board can be done by connecting it to a PC using a USB cable, or battery or an AC-DC adapter. This board mainly includes everything which is essential for supporting the microcontroller. It includes digital input/output pins-54, where 16 pins are analog inputs, 14 are used like PWM outputs hardware serial ports ( UARTs) – 4, a crystal oscillator-16 MHz, an ICSP header, a power jack, a USB connection, as well as an RST button. The microcontroller board like “Arduino Mega” depends on the ATmega2560 microcontroller.
