21st Century Learning and Teaching

This tutorial shows how to use Server-Sent Events (SSE) in an ESP8266 NodeMCU Web Server programmed with Arduino IDE. SSE allows the browser to receive automatic updates from a server via HTTP connection. This is useful to send updated sensor readings to the browser, for example. Whenever a new reading is available, the ESP8266 sends it to the client and the web page can be updated automatically without the need to make additional requests.

In our case, we use NODEMCU ESP8266, but you can use any other type of ESP8266 with all pins exposed. In our program, we connect D0, D1, D2, and D3 in a circuit, which controls the relays. The relays are using 5V. ESP8266 is using 3.3V. To connect the 3.3V ESP8266 to the 5V relay module, we use one NPN transistor 2N2222.

Text on I2C-LCD1602 Display written over Web-Page Sometimes it might be useful to write a text which should be displayed on a LCD display without any cabling, that is possible to do over your own Wi-Fi network and a NodeMCU ESP8266 module. And the project uses ONLY 4 wires as the LCD1602 gets…

A GOOD preparation is half the work done! When we play around with Arduino NANO, NodeMCU, ESP8266 and others it is important (and more comfortable) to make us life as less difficult as necessary. Therefore we will have a look on the How-To, using some helpful tools.

Hi, in this tutorial we will see how to control electrical devices like fan, light, etc., to turn on and off using esp8266 from a web browser. if you are bored with a dedicated device controller like an app or an remote which will be available for only one particular device but using this method all the device which support web browsing will be act as a  controller for us.

Make sure all the devices are connected to the same router, this example doesn't include a port forwarding function which will not allow us to control the device from outside the home network. 

Components that you need for completing this project are very simple, you need to have an esp8266 wifi module and a relay, make sure you buying a 5v relay which very easy to use with esp chips doesn't require external supply too. we can make use of the Vin pin of the nodemcu or if you are using a generic chip, you need to supply an external 5v to the relay.

This tutorial shows how to use the I2C LCD (Liquid Crystal Display) with the ESP32 using Arduino IDE. We’ll show you how to wire the display, install the library and try sample code to write text on the LCD: static text, and scroll long messages. You can also use this guide with the ESP8266.
