4 Implementing Arduino Code Using Gemma M0 and Circuit Playground

Gemma M0, Circuit Playground, and other sewable boards are a great way to add more interaction to your wearables. As you learned in the previous chapter, their different sizes, functions, and I/O ports make them appropriate for different uses.

In this chapter, we will focus on learning through building a practical application with a Gemma M0 or Circuit Playground board so that you can expand the capabilities of your circuit. We will also explore flex sensors and the many ways to alter, use, and make them. Once you’ve considered their uses, you will connect a circuit. We will also read about how flex sensors have been used in research. Reading how components are used is a great ...
