Hello! I'm a newbie in arduino so please excuse me for the silly question if it is
I have arduino nano and need two serial ports to communicate with computer, I have one program "sitting" on one port and need another program to "sit" on another. The first program is proprietary and I don't have it's source code so I could add code from second program so they could share one port... Long story short - I need another serial port to communicate with computer on nano v4.
I've found NewSoftSerial library and going to do as follows: 1) in arduino code add serial like this: NewSoftSerial mySerial(4,3); 2) connect computer's TX -> D4 on arduino, RX -> D3
then start working with mySerial. Can I go like this? Or do I need to add some RC components? Sorry for the stupid question if it is, thanks!
