Elements and Interface / Elemanlar ve Arayüzler

Here is an explanation of what every element and interface of the board does:

	Digital I/O Arduino MEGA has 54 digital input/output pins (of which 15 can be used as PWM outputs). These pins can be configured as digital input pin to read the logic value (0 or 1). Or used as digital output pin to drive different modules like LED, relay, etc. Using pinMode(), digitalWrite(), and digitalRead() functions.
	GND Ground pins
	AREF Reference voltage (0-5V) for analog inputs. Used with analogReference(). Configures the reference voltage used for analog input (i.e. the value used as the top of the input range).
	SDA IIC communication pin
	SCL IIC communication pin
	ICSP (In-Circuit Serial Programming) Header the AVR, an Arduino micro-program header consisting of MOSI, MISO, SCK, RESET, VCC, and GND. Connected to the ATMEGA16U2-MU. When connecting to PC, program the firmware to ATMEGA16U2-MU.
	USB Connection Arduino board can be powered via USB connector. All you needed to do is connecting the USB port to PC using a USB cable.
	D13 LED There is a built-in LED driven by digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.
	ATMEGA 16U2-MU USB to serial chip, can convert the USB signal into serial port signal.
	TX LED Onboard you can find the label: TX (transmit) When Arduino board communicates via serial port, send the message, TX led flashes.
	RX LED Onboard you can find the label: RX(receive ) When Arduino board communicates via serial port, receive the message, RX led flashes.
	Crystal Oscillator How does Arduino calculate time? by using a crystal oscillator. The number printed on the top of the Arduino crystal is 16.000H9H. It tells us that the frequency is 16,000,000 Hertz or 16MHz.
	Voltage Regulator Convert an external input DC7-12V voltage into DC 5V, then switch DC 5V to the processor and other components. Output DC 5V, the drive current is 2A.
	DC Power Jack Arduino board can be supplied with an external power DC7-12V from the DC power jack.
	IOREF This pin on the board provides the voltage reference with which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V.
	RESET Header Connect an external button to reset the board. The function is the same as reset button.
	Power Pin 3V3 Provides 3.3V voltage output
	Power Pin 5V Provides 5V voltage output
	Vin You can supply an external power input DC7-12V through this pin to Arduino board.
	Analog Pins Onboard has 16 analog inputs, labeled A0 to A15.
	RESET Button You can reset your Arduino board, for example, start the program from the initial status. You can use the RESET button.
	ICSP (In-Circuit Serial Programming) Header the AVR, an Arduino micro-program header consisting of MOSI, MISO, SCK, RESET, VCC, and GND. It is often called the SPI (serial peripheral interface) and can be considered an "extension" of the output. In fact, slave the output devices to the SPI bus host. When connecting to PC, program the firmware to ATMEGA2560-16AU.
	Microcontroller Each Arduino board has its own microcontroller. You can regard it as the brain of your board. The main IC (integrated circuit) on the Arduino is slightly different from the panel pair. Microcontrollers are usually from ATMEL. Before you load a new program on the Arduino IDE, you must know what IC is on your board. This information can be checked at the top of IC.
	Power LED Indicator Powering the Arduino, LED on means that your circuit board is correctly powered on. If LED is off, connection is wrong.

Specialized Functions of Some Pins / Bazı Pinlerin Özel Fonksiyonları

• Serial Communication: D0 (RX0) and D1 (TX1); Serial 1: D19 (RX1) and D18 (TX1); Serial 2: D17 (RX2) and D16 (TX2); Serial 3: D15 (RX3) and D14 (TX3).

Used to receive (RX) and transmit (TX) TTL serial data. Pins 0 and 1 are also connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip.

• PWM Pins (Pulse-Width Modulation): D2 to D13, and D44 to D46.

Provide 8-bit PWM output with the analogWrite() function.

• External Interrupts: D2 (interrupt 0), D3 (interrupt 1), D18 (interrupt 5), D19 (interrupt 4), D20 (interrupt 3), and D21 (interrupt 2).

These pins can be configured to trigger an interrupt on a low level, a rising or falling edge, or a change in level. See the attachInterrupt() function for details.

• SPI communication: D53 (SS), D52 (SCK), D51 (MOSI), D50 (MISO).

These pins support SPI communication using theSPI library. The SPI pins are also broken out on the ICSP header, which is physically compatible with the Arduino Uno.

• IIC communication: D20 (SDA); D21 (SCL). Support TWI communication using the Wire library.

Tips / İpuçları

• Automatic (Software) Reset:
  

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

• The Mega 2560 board contains a trace that can be cut to disable the auto-reset. The pads on either side of the trace can be soldered together to re-enable it. It's labeled "RESET-EN". You may also be able to disable the auto-reset by connecting a 110 ohm resistor from 5V to the reset line; see this forum thread for details.

int val;//define variable val
int ledpin=13;// define digital pin13
void setup()
{
Serial.begin(9600);// set the baud rate at 9600. When connected to a specific device, (e.g. bluetooth), the baud rate needs to be the same with the device.
pinMode(ledpin,OUTPUT);// initialize digital pin 13 as output. When using I/O ports on an Arduino, this kind of set up is always needed.
}
void loop()
{
val=Serial.read();// read the instruction or character from PC to Arduino, and assign them to Val.
if(val=='R')// determine if the instruction or character received is an "R”.
{  // if it’s "R”,    
digitalWrite(ledpin,HIGH);// set the LED on digital pin 13 on. 
delay(500);
digitalWrite(ledpin,LOW);// set the LED on digital pin 13 off.
