Arduino Uart Serial Connection
Intro: Arduino Bluetooth Serial Connections. - I made it at TechShop. This is an introduction on how to setup, make a basic connection, and send data to and from an.
UART TTL, Half Duplex, supported baud rate from 1200bps to 115200bps, default is 9600bps.
FT232RL USB to Serial UART TTL Adapter is a simple and inexpensive way to connect PIC, AVR or ATMEGA MCUs to a PC or Mac via USB connection.

Receives from the hardware serial, sends to software serial.
Receives from software serial, sends to hardware serial.
The circuit:
RX is digital pin 10 connect to TX of other device
TX is digital pin 11 connect to RX of other device
Note:
Not all pins on the Mega and Mega 2560 support change interrupts,
so only the following can be used for RX:
10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69
Not all pins on the Leonardo support change interrupts,
8, 9, 10, 11, 14 MISO, 15 SCK, 16 MOSI.
