I created an Internet of Things smart box for ExitShop to display the current number of orders and, most importantly, play a melody (like Super Mario) when a new order arrives.
It’s basically a NodeMCU with a small OLED display, buzzer, and LED. It runs a script that periodically queries the ExitShop endpoint via http.
There’s also a C# uploader that’s a console application where you enter the settings, compile the program, and upload it to the NodeMCU using the console Arduino IDE.
On GitHub, you can find the complete source code and descriptions of various prototypes I’ve created so far :)
