esp8266-nodemcu-uart-bridge provides an ESP8266 NodeMCU Lua application (init.lua) that mirrors incoming MQTT messages to the ESP8266's UART and can also transmit messages received by UART to an MQTT ...

This code and corresponding tutorial explain how to communicate between two ESP8266 NodeMCU's via a wired UART connection rather than using WiFi. There are a number of reasons you might want to do ...

Blockchains claim to be public, distributed, effectively immutable ledgers. Unfortunately, they also tend to get a little bit huge – presently the Bitcoin blockchain is 194GB and Ethereum weighs in at ...

The Espressif ESP8266 chipset makes three-dollar ‘Internet of Things’ development boards an economic reality. According to the popular automatic firmware-building site nodeMCU-builds, in the last 60 ...

Abstract: This paper presents the design and implementation of an automatic crop irrigation system based on a NodeMcu ESP8266 microcontroller integrated with the Blynk platform. The system is designed ...

Abstract: The aging population faces significant risks from falls, often leading to fractures, head injuries, and extended hospitalization. To mitigate these dangers, an integrated solution combining ...
