In this user guide, we will learn to send sensor readings to Google firebase and also on Android app through Google Firebase using ESP8266 NodeMCU and Arduino IDE. We will make our personal ESP8266 IOT app by using Google Firebase and MIT App Inventor. Previously, we used the Blynk application to control ESP32’s output (Control … Read more
In this tutorial, we will learn to interface the BME680 sensor with Arduino using Arduino IDE. The BME680 environmental sensor, which is used to measure ambient temperature, barometric pressure, relative humidity, and gas (VOC) or Indoor air quality (IAQ). We will learn how to interface it with Arduino using Arduino core programming. For demonstration, firstly, … Read more
In this tutorial, we will learn to program ESP32 and ESP8266 boards with VS code by using the Pymakr extension available in visual studio code. As we have seen in previous tutorials, we have learned to program ESP32 and ESP8266 boards using various IDEs. Recommended Components The following components are used in this project or … Read more
In this user guide, we will learn about web server with Server-Sent Events (SSE) protocol. Using this technique, we will build an ESP8266 controlled web server that will automatically update sensor readings regarding temperature, pressure, and humidity to all connected web clients. Our client will receive automatic updates from the ESP8266 board with SSE through … Read more

In this user guide, we will control the output of the ESP32 using the Blynk application installed in our smartphones. Previously, we controlled the ESP module’s outputs through applications such as Telegram and Google Firebase. You can view the tutorials by accessing the links below: Telegram ESP32 and ESP8266: Control GPIOs and LEDs using Arduino … Read more
In this tutorial, we will learn how to get the current date and time from the NTP server with the ESP8266 NodeMCU development board and Arduino IDE. In the data logger applications, the current date and timestamp are useful to log values along with timestamps after a specific time interval. The time.h header file provides … Read more
In this tutorial, we will learn how to reconnect the ESP8266 NodeMCU board to the WIFI network when it temporarily loses connection. Through different methods, we will demonstrate this functionality. Hence, this guide will be highly useful to avoid the nuisance of constantly losing network connection due to many reasons such as WiFi router restarted, … Read more
In this tutorial, we will create an ESP8266 NodeMCU web server by using a WebSocket communication protocol and Arduino IDE that will control the onboard LED of ESP8266 NodeMCU. Through WebSocket communication protocol, several clients can be connected to the server concurrently without blocking each other. We will see that unlike HTTP, a websocket server … Read more
In this user guide, we will focus on building an async web server. The web server will be created in ESP8266 NodeMCU using Arduino IDE through the ESPAsyncWebServer library. The web server will allow the user to control multiple LEDs connected with the ESP8266 NodeMCU GPIO pins simultaneously by using HTTP GET requests to transfer … Read more
