I’m giving some workshops in electronics in a few weeks, centered around an inexpensive, but useful real-world project. When trying to come up with a thing to make, I wanted it to involve a microcontroller, NeoPixel LEDs (because, they’re awesome), be remotely controllable, and allow for different build options. It also had to be fully simulatable in Autodesk Circuits. This is the project that evolved.
