Case Project 13-2
You’ll need a wireless network adapter such as ESP8266 or ESP32 to add to the project or change the
microcontroller board to one with a built-in adapter. You can get microcontroller development boards with
built-in ESP8266 or ESP32 controllers that are Arduino-compatible.
Case Project 13-3
Answers will vary, but you probably want an SBC such as a Raspberry Pi. The Raspberry Pi has a Wi-Fi
