Home Automation using ESP8266 & Blynk App - Practical Implementation

Home Automation using ESP8266 & Blynk App – IoT

A home automation system is an automating the bulk of electronic and electrical tasks within a home. It uses a combination of hardware and software to enable control and management over appliances and devices within a home. Home automation not only refers to reduce human efforts but also energy efficiency and time saving. Here we are performing home automation by using ESP8266 – WiFi SoC and Blynk Playstore App. Components RequiredESP8266 470Ω Resistor LED Breadboard USB Cable Connecting Wires Android Phone with Blynk AppHardware Circuit Diagram Home-Automation-using-using-ESP8266-Blynk-App-Circuit-Diagram Circuit Diagram Explanation NodeMCU to 4- Channel Relay BoardConnect [...]

ESP8266 as MQTT Client - Arduino IoT Tutorial

ESP8266 as MQTT Client – Arduino IoT

IoT or Internet of Things is an emerging technology which enables us to create a network of devices, sensors, actuators to connect and exchange data. MQTT (Message Queuing Telemetry Transport) is one of the commonly used protocol in this field. It consists of MQTT Broker and MQTT Clients. Where MQTT Broker is the server through which all MQTT Clients are communicating each other. CloudMQTT provides MQTT Broker as a service, which we are using in this tutorial. In this project [...]
