What can I do with a 20 cent microcontroller?

The CH32V003 microcontroller has been around for a while, but I only recently learned about it. It's incredibly affordable and very capable. Today I'm doing some first explorations of this interesting little chip (and did I mention that it only costs 20 cents! ) I'm using the Arduino IDE because that is what I'm familiar with. There are, of course, other IDEs available which other people may prefer. Get some here: https://pileofstuff.ca/r/1jhey And the programmer: https://pileofstuff.ca/r/am6bp Thanks to OneCircuit for triggering my interest in this microcontroller: https://onecircuit.blogspot.com/2024/08/0000-0000-1110-1111.html This is the board definition for the CH32V003 family of microcontrollers.
