SPI Pins 10 (SS), 11 (MOSI), 12 (MISO) and 13 (SCK):В These pins are used for SPI communication.PWM Pins 3, 5, 6, 9 and 11:В These pins provide an 8-bit PWM output by using analogWrite() function.External Interrupt Pins 2 and 3:В These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.

They are connected with the corresponding ATmega328P USB to TTL serial chip.

Serial Pins 0 (Rx) and 1 (Tx):В Rx and Tx pins are used to receive and transmit TTL serial data.

Out of these 14 pins, some pins have specific functions as listed below: Each pin operate at 5V and can provide or receive a maximum of 40mA current, and has an internal pull-up resistor of 20-50 KOhms which are disconnected by default. Serial Call Response ASCII - Send multiple variables using a call-and-response (handshaking) method, and ASCII-encode the values before sending.The 14 digital input/output pins can be used as input or output pins by using pinMode(), digitalRead() and digitalWrite() functions in arduino programming. Serial Call Response - Send multiple vairables using a call-and-response (handshaking) method. MultiSerialMega - Use two of the serial ports available on the Arduino Mega. SoftwareSerialExample - Two serial ports that route data between them mirroring TX and RX. SoftwareSerial portTwo ( 8, 9 ) void setup ( ) // blank line to separate data from the two ports:

This example code is in the public domain. Not all pins on the Leonardo support change interrupts,ДЁ, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI). Not all pins on the Mega and Mega 2560 support change interrupts, * Second serial device's TX attached to digital pin 8(RX), RX to pin 9(TX)

* First serial device's TX attached to digital pin 10(RX), RX to pin 11(TX) Two devices which communicate serially are needed. This example switches ports when there is nothing Ports, like the end of an expected transmission, or when theД«uffer is empty. When using two software serial ports, you have to switch portsД«y listen()ing on each one in turn. In order to listen on a software port, you call port.listen().

Receives from the two software serial ports, For more circuit examples, see the Fritzing project page Code For more circuit examples, see the Fritzing project page Schematics Make sure that your Arduino board is attached to your computer via USB to enable serial communication through the serial monitor window of the Arduino Software (IDE). After that, it does the same on the second virtual port (portTwo). The board listens on one virtual port (portOne) until it has read all available data. In the example below, digital pins 8 and 10 on your Arduino board are used as virtual RX serial lines. This can be extremely helpful when the need arises to communicate with two serial enabled devices, or to talk with just one device while leaving the main serial port open for debugging purpose. Arduino boards have built in support for serial communication on pins 0 and 1, but what if you need more serial ports? The SoftwareSerial Library has been developed to allow serial communication to take place on the other digital pins of your boards, using software to replicate the functionality of the hardwired RX and TX lines.
