What might be best is to show some of the videos on the website as that gives a good introduction into what you can do too.
In addition to the website videos, there's also a YouTube channel full of Qt goodies: https://www.youtube.com/playlist?list=PLizsthdRd0YykOJsqikaW-OCF3r7OXRB5

Please also refer to QSerialPort sample.
