This book gives you the low-down on microcontrollers by learning how to use the Express with Microsoft MakeCode and CircuitPython. You'll also learn how to configure your board and have fun in the Arduino IDE! Also includes a forward from Limor "Ladyada" Fried (designer of the Circuit Playground)
"...We poured all the know-how and experience we've had over 10 years of selling educational electronics to create something for everyone. Whether you want to build cosplay props, scientific experiments, robotics, or spy gadgets– in drag-n-drop Microsoft MakeCode, interpreted CircuitPython, or Arduino– Circuit Playground Express will be your companion as you learn and create."
Who is this book for? Great question!
"This book is for the enthusiast, the student, the curious person who wishes to expand their knowledge of making through interactivity, sensing, lights, sound... Working with Circuit Playground Express is suitable for beginners who do not know electronics or programming. After you finish reading, you can use this book as a reference for the techniques presented."
The pace is also good for teachers/instructors to get people familiar with programmable microcontrollers.

Adafruit NeoPixel Digital RGB LED strips come to us in 4 or 5 meter reels with a 2 or 3-pin JST SM connector on each end and separated power/ground wires as shown in the picture below. If you order a full 4 or 5 meters, you get the full reel with both connectors installed.
If you buy less than a full reel, you'll get a single strip, but it will be a cut piece from a reel which may or may not have a connector on it. If the piece comes from the end of the reel, the connector may be on the output end of the strip!
