What can I do with a 20 cent microcontroller?

Описание: 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.

And the programmer: https://pileofstuff.ca/r/am6bp

Thanks to OneCircuit for triggering my interest in this microcontroller:

This is the board definition for the CH32V003 family of microcontrollers. Paste this link into your Arduino IDE

If the programming board is being weird, here is some troubleshooting steps:

This isn't the only way to do it.
It's probably not the best way to do it.
But it's how I did it.
