When we first heard about it a few weeks ago, we knew the ESP8266 UART to WiFi module was a special beast. It was cheap, gave every microcontroller the ability to connect to a WiFi network, and cou… ...

Despite a wealth of tutorials for setting up and writing code for the ESP8266 WiFi module, there has not been much of anything on programming this cheap wireless module with the Arduino IDE. Finall… ...

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 ...

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 ...
