A collection of simple Arduino examples for using the NodeMCU (ESP8266) within the Arduino programming environment (IDE).
Be aware: Input voltage range of bare ESP8266 is 0—1.0V. The operating Voltage is 3.3V. Therefore the NodeMCU (v1.0) has a voltage-divider circuit at Pin A0. If you have a different Board-Setup please ...

Hands-On: The RISC-V ESP32-C3 Will Be Your New ESP8266
It’s not as newbie-friendly as ESP-Arduino, for sure, but it’s a ton more powerful, and we’re totally happy to leave the ESP8266 SDK behind us. The ESP32-C3 shares the coding framework with ...
