7 Moving Forward with Circuit Design Using ESP32

In this chapter, we will delve deeper into designing circuits using alternative microcontrollers. These are circuit boards that aren’t specifically “sewable,” but we can use them for wearables. Using ESP32 will add more interactivity to our sewable circuits. It’s a powerful and adaptive microcontroller board. Although the ESP32 development board form factor is not typically made for a wearable project, we’ll look at how we can add them and why this is beneficial. Using these techniques, you can adapt other microcontroller boards and components to your future wearable projects too. We will learn to program these boards using Arduino software.

In this chapter, we will learn about the ESP32 board. ...
