Goodreads asked Rick Leander:

Where did you get the idea for your most recent book?

Rick Leander I needed something to do while in lock-down for COVID-19, and had always wanted to try writing a Kindle book. I’d been playing with several microcontroller boards and decided that a collection of microcontroller projects would be a good place to start. The result was ‘Make Music with the Circuit Playground Express. It was so much fun that ‘Ten Games with the Circuit Playground Express’ went online about six weeks later.
