Flashing Espressif and NodeMCU Firmware to ESP8266

In the earlier articles, we have written our own program in Arduino IDE to access GPIO pins of ESP8266 or to interface sensors to ESP8266. But if we write our own program to access GPIO Pins, the existing firmware will be completely erased and the new program will be written on the ESP8266. So in this article, we will explain how to flash the Official Espressif and NodeMCU Firmware to ESP8266. This can also be used to update to the latest [...]

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 [...]

Interfacing DHT11 Sensor with ESP8266 - Practical Implementation

Interfacing DHT11 Sensor with ESP8266

In this article, I am going to explain about interfacing of DHT11 sensor with ESP8266. For that we have to make only 3 connections between the DHT11 sensor and ESP8266. For the working demonstration we will be programing ESP8266 as a web server for displaying temperature and humidity in a web browser as per request. Components RequiredESP8266 DHT11 Sensor USB Cable Connecting WiresHardware Circuit Diagram Interfacing DHT11 Sensor with ESP8266 – Circuit Diagram ConnectionsDHT11 sensor (+) pin will be connected to 3.3V DHT11 sensor (-) pin will be connected [...]
