How it works...

When you click on the Serial button in the Mu editor, it will attempt to open a serial connection to the board. If successful, it captures your input, sends it the device, and displays the output just as a typical Terminal emulator would.

The beauty of this application is that it works on all the major desktop OSes and automatically finds the correct device address without the need to manually specify it, as is required by your typical Terminal emulators. It also has a very simple and approachable layout, making it easy to use for first-time users to connect to microcontrollers.
