Create a PyQt tray icon to send UDP Datagram
I have an Arduino (with an infrared LED pointing my HiFi) attached to FritzBox via USB. I can control it by sending UDP packet to FritzBox, what better way to send UDP Command to it than a tray icon?
I used a simple Python script that use PyQt to display tray icon, "the radio":
When you rolling the wheel of your wheel mouse on the icon, it sends UPD packet to get volume up and down. With a double click it sends "mute" command and with right click it show up all command that you can send to HiFi.
This is the script for Linux, using PyQt4:
This is the script for Windows, using PyQt5:
