Introduction

FLORA is Adafruit's wearable electronics platform. It's built around the Arduino Atmega32u4 chip and has built-in USB support. According to Wikipedia (Aug 2019), “Adafruit Industries is an open-source hardware company based in New York City. It was founded by Limor Fried in 2005. The company designs, manufactures and sells a number of electronics products, electronics components, tools and accessories. It also produces a number of learning resources, including live and recorded videos related to electronics, technology, and programming.”

The FLORA is an alternative to the Lilypad

Circuit Playground Express

Playground express are interesting for education since the board can be programmed with MakeCode, JavaScript or CircuitPython. In addition, it can communicate with other boards through the infrared sensor. In addition to the built-in LEDs and sensors, one also can attach external components.
