In some other Arduino boards, like Mega, there are several different available UARTs. But for Arduino Uno, you only have one. If however, you want to use more UARTs, you can always do that with theSoftwareSerial library. This library allows you to use any other digital pins for UART pur...

PINx: Port Input Register: This byte contains the state of the digital inputs. If the pin is an output, it will just give you the output state. In the image above, you can see the entirepin mappingof the Arduino Uno, the port numbers are in the yellow fields next to the pins. (...
