The next step is to start your own experiments with ESP-01. For examples, the Arduino core for ESP8266 comes with plenty of interesting sketches to fiddle with! Note: As described earlier, when trying ...

The ESP-01 launched the ESP8266 revolution back in 2014, and while today you’re far more likely to see somebody use a later version of the chip in a Wemos or NodeMCU development board, there … ...

This dev board is explicitly designed to work with the NodeMCU firmware, a Lua-based firmware for the ESP. Already we’ve seen some projects make the Hackaday front page with this firmware.

Seemingly, this ESP-01 Wi-Fi Relay can be used as a smart on/off switch for handling any device connected to it. When a pre-programmed ESP module is inserted into the relay board, it not only serves ...
