Communication
Software UART for Arduino
This library allows any pair of pins to be used as a UART implemented by software. The MCCI version incorporates bug fixes and makes it more compatible with the UART and USB serial classes.
Maintainer: Terry Moore
This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
