The live GPIO pin monitoring library sets up the ESP32 to stream information about what all of the pins are doing in real time to a webserver, which displays the information as a helpful graphic.

The coolest option, though, is “GPIO” which then leads to a matrix that connects any of the digital hardware peripherals to that pin. Want UART2 RX on pin 13? No problem, just set it up in code.

As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for super cheap, and they're incredibly versatile. When you're done using an ...
