Allow me to introduce myself. I am Mark and live in Tucson Arizona. I am a retired electrical and reliability engineer and have been working with Arduinos off and on now for 10 years.
I recently completed several projects using NeoPixel LEDs. One was a light box which illuminates a plastic sculpture using a NeoPixel shield. It is controlled by 3 potentiometers. The second uses a NeoPixel Gem along with an Arduino Nano Every. It uses a pushbutton to cycle through various modes and fits in a small box beneath a selenite crystal that sits on the mantel.
I am interested into getting into much more advanced work, possibly some assembly language code. The Nano Every uses a MEGA4809 microcontroller which has some advanced capabilities such as configurable logic.
