It’s a powerful 32-bit processor with multiple I/O ports. 12-bit A/D converters and a variety of interfaces. But the one thing that makes it stand out above the crowd is its built-in WiFi and Bluetooth capabilities. When we experiment with the ESP32 WiFi we generally just hard-code our WiFi login information directly in our sketches. Some people use an external file, but it is just another way to accomplish the same thing. In both cases, our code is compiled and loaded onto our ESP32, so the ESP32 is locked into using that WiFi SSID and password. If you want to change these parameters to
