Arduino Uno Pinout Serial Serial Port Available
Really, it IS the Arduino. Serial0 can read and write data on pins 0 and 1 of the external pinout.The 328P is the processor chip on the Arduino. MICROCONTROLLER USED IN ARDUINO UNO IS ATMEGA328In Arduino UNO the Serial object implements an UART serial port available both. Power and USB: There is a USB type-B Port on the board which is used to program and power the microcontroller IC also there is a separate power input port to give external voltage via regulator 7805. Checkout here for Introduction To Arduino Uno tutorials. Here is an image showing various pinouts of Arduino Uno.
RS-232 Maximum Cable Length. This, in turn, communicates with the 328P.RS232 DB9 Pinout Diagram. The more technical explanation: your computer communicates with a USB to U(S)ART serial adapter. You program this chip whenever your program your Arduino Uno.
