Learn how to publish BME680 sensor readings via MQTT with the ESP8266 NodeMCU to any platform that supports MQTT client. We'll publish sensor readings to Node-RED.
To enable ESP8266 firmware flashing GPIO0 pin must be pulled low before the device is reset. Conversely, for a normal boot, GPIO0 must be pulled high or floating. If you have aNodeMCU dev kitthen you don't need to do anything, as the USB connection can pull GPIO0 low by asserting D...
In this guide, you’ll learn how to create and use a web-based “Serial Monitor” for your ESP8266 NodeMCU projects using the WebSerial library. This creates a web-based interface to output debugging messages, as you would do with a regular serial monitor. You can also send messages from...
Pin layout LoLin NodeMCU development board V3. Source: http://www.wemos.cc/wiki/Hardware/Pin If you compare the pin layout there’s only a tiny difference to the V2 layout. LoLin decided to use one of the two reserve pins for USB power out and the other for an additional GND. Watch ...
