To use this book and the Adafruit FLORA board, first, read through the book to understand the basics of wearable electronics. When you start planning your circuits, think about what functions you want your wearable to have. While sewing with electronics, be careful not to damage the components. When writing programs for the FLORA, start with simple ones and gradually add more complexity. As for maintenance, keep the FLORA board dry and away from dust. If you're using sensors or RGB LEDs, check their connections regularly to make sure they're working properly. Enjoy creating your unique wearable projects!
