This is a working Among Us taskbar in the browser.

Using the javascript Paho MQTT library, this thing reliably fills up when receiving in a certain MQTT topic.

HTML, CSS, JS

To limit the scope of the project, 3 of the most interesting possible options have been chosen.

I am ranking them in complexity like this (low to high):

1. "Rocket" ... to make the underlaying interaction only 4 leds and 4 buttons are required.
2. "Levels" ... requires 4 sliders which are more expensive but easy to implement. Feedback whether being right or wrong could come in the form of an LED or sound.
3. "Card Swipe" ... requires a more delicate hardware-build with sensors to catch a (credit-)card swipe and is one of the most infamous tasks of the game.

To make the interactions more appealing, I believe a buzzer/speaker for chimes should make it much more enjoyable. This would be added to all mini-games.

Sound feedback can be related directly to the interaction or indicate error and success.

To help with evaluating and filtering through all the possibilities a complete list of all tasks has been made.

What is actually possible to make?

The goal is to make systems which don't rely on mouse+keyboard or touchscreen interfaces. Those aren't really interesting for electronics teaching because it would lack the focus on physical circuitry.

Therefore all possible mini-games get tagged with the electronics parts and the complexity to later show a cross-section of easy and cheap to make options.
