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.

ESP8266 modules are great low cost stand alone controllers with built in Wi-Fi. In this Instructable I will show you how you can control a Servo remotely over Wi-Fi with a Rotary Encoder. The Instructable is a similar but more advanced version of the "Arduino Nano and Visuino: Control Servo with Rotary Encoder" Instructable.

In the Instructable, I will use 2 NodeMCUmodules. One version 0.9, and the other 1.0. The NodeMCU are the easiest way to program and experiment with ESP8266controllers. This Instructable however can easily be done with other modules, and the Servo module can even use ESP-01 module as it needs only one GPIO pin to connect to the Servo.

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.

This guide will help you understand how to get started using Blynk and give a comprehensive overview of all the features.

If you want to jump straight into playing with Blynk, check out Getting Started.

How Blynk Works

Blynk was designed for the Internet of Things. It can control hardware remotely, it can display sensor data, it can store data, vizualize it and do many other cool things.

In this new tutorial on Cayenne IoT, we will learn how to control an articulated Pan-Tilt PTZ SG90 system in WiFi. In the previous tutorial, we saw how to do with the Blynk library and application. Cayenne IoT is fairly similar. It is necessary to pass through the servers of myDevices.com which can cause a small delay of latency (quality of Internet connection, server load …).

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.

What will you make:

In this article, we will learn how to monitor temperature and humidity with your smartphone device, using a platform called Blynk. Blynk allows you to control Arduino, ESP8266, Raspberry Pi and other such boards through their iOS and Android apps. It provides an easy to use dashboard through which you can monitor various sensors and control actuators. If you are completely new to Blynk, checkout our Getting Started with Blynk guide.
