Arduino Serial Example #4 Remote Control Blink Using Software Serial: Master char mySecondCharacter = Serial. So, in such cases, there’s a need to add one more serial port and that serial port can be created at any two pins of Arduino and is called software serial.A simple and robust serial communication protocol. One of the serial communication methods is UART, the word UART stands for Universal Asynchronous Receiver / Transmitter. JanuIf you are attempting to use an Arduino Nano on a Windows machine and having no luck finding drivers automatically, chances are it is due to a counterfeit FTDI chip which unfortunately does not work with the automatic driver finding functionality in Windows. For details, see the reference and tutorials. If you have another Arduino you can use that as serial/usb converter. Sign up for free to join this conversation on GitHub. Another serial port is created with the Software Serial library, using pins 11 and 12.

The native serial support happens via a piece of hardware (built into the chip) called a UART. The ATmega168 or ATmega328 on the Arduino Nano comes with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. This port sends the data to a second remote Arduino over RS485. Enables the selected software serial port to listen. 11 Extract the downloaded folder, downloaded in step 3. Only one software serial port can listen at a time data that arrives for other ports will be discarded. read() Then mySecondCharacter would be holding the value “u”, and “b Sandwich” would be left in the serial receive buffer. The Arduino Mega has four hardware serial ports that can communicate with up to four different serial devices.
