This project demonstrates how to control a relay module using an ESP8266 microcontroller. A relay is an electromechanical switch that allows low-power circuits to control high-power devices. The ...

#define DO_LATCH 0 // set to 1 to allow latching relay 3&4 (need to change index.h as well) #define SKIP_DELAY 0 // set to 1 to skip startup delay ...

In this IoT projects, I have shown you how to make the smart home with Google Assistant & Alexa using NodeMCU ESP8266 to control relays with voice commands and manual switches. I have used all the ...

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 could ...

Abstract: The Internet of Things (IoT) is experiencing rapid growth and being adopted across multiple domains. For example, in industry it supports the connectivity needed to integrate smart machines, ...

ESP8266 development boards like the Wemos D1 Mini and NodeMCU are an excellent way to get a one-off project up and rolling quickly, but their size and relative complexity mean they aren’t necessarily ...

HackBat is an open-source hardware pen-testing device designed for hackers and makers and equipped with a Raspberry Pi RP2040 microcontroller, an ESP8266 WiFi module, a sub-GHz RF transceiver, NFC, an ...
