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.

In this project you’ll create a standalone web server with an ESP8266 that displays the temperature and humidity with a DHT11 or DHT22 sensor using the Arduino IDE. The web server you’ll build can be accessed by any device that has a browser on your local network.

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.

Exchange any data between Blynk app and your hardware.

Virtual Pin is a concept invented by Blynk Inc. to provide exchange of any data between hardware and Blynk mobile app. 

Virtual pins are different than  Digital and Analog Input/Output (I/O) pins. They are physical pins on your microcontroller board where you connect sensors and actuators.

Blynk lets you control any hardware connected to Digital and Analog pins without having to write any additional code.

For example, if you need to turn On/Off LED connected to Digital pin, you don't have to write any code: 

1. Just use BlynkBlink code for your hardware. 
2. In the Blynk app - add Button Widget and set it to pin D8
3. That's it! No additional code is required. Simply press Play in the app.

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 …).

Der NodeMCU ESP8266 ist wohl derzeit das Lieblings-Controller-Board vieler Bastler. Denn es vereint viele Vorteile unter einem Dach. Hier ein kleiner Auszug, was zum Erfolg des NodeMCU ESP8266 geführt hat:

• kompakt und klein
• WLAN on Board
• viel Speicherplatz
• USB-Schnittstelle (Bootloader) 
• lässt sich über Arduino IDE programmieren
• große Anzahl an Schnittstellen

Tja, und um genau diese Schnittstellen geht es hier in diesem Beitrag.

Hier zeigen wir Euch z.B. wo welche GPIO Ports liegen, wo ihr den Ground findet, an welcher Stelle das Board 3,3 Volt liefert. Welche PIN Stecker für RX und TX verwendet werden können – einfach alles, was man so über die PINs des NodeMCU ESP8266 wissen muss.

About this Project:

In this project we will learn how to interfacing ESP8266 module with MAX7219 matrix display to scrolling text message from web user interface. We will use Arduino IDE to program ESP module in this project. I am using MajicDesigns MD_MAX72xx library for running this project, also the code is very similar to included example in the library with some improvements in web user interface html code.

Aside from cool cat feeders, it is possible to find multiple maker projects for controlling garage doors, blind windows, smart locks, tracking cars, control temperature and humidity levels, and so on. However, the security aspect of these devices needs to take some extra attention, starting from the connection between the device and the Cloud infrastructure.

Most microcontrollers today are not powerful enough to handle secure connections, like SSL or TLS, so all the communication between the device and the server is open to attacks, like sniffing values, tacking device credentials, faking values, granting unauthorized access to physical facilities, unlocking doors, and many other possibilities. This way, securing the communications for all the Internet-connected devices should be a priority, especially if they can jeopardize our security or privacy.

The security of the Internet of Things does not only rely on secure communications, but it is a great start. The maker community must be aware of the security concerns of untrusted communications, and must have the appropriate resources to handle it. This way it is common to see different alternatives to offer secure communications in the microcontrollers, like porting SSL/TLS libraries to cheap devices like ESP8266, or device vendors that already integrates a crypto chip that process all this stuff by hardware, like the recent Arduino MKR1000.

In thinger.io we are concerned about this security aspect, so our cloud supports secure connections for any device with this capability. In the recent Arduino library update, starting from version 2.4.1, we have introduced support for the Arduino MKR1000, including secure TLS connections by default. Just start with the following sample sketch for the MKR1000, and you will have encrypted connections by default.

Want to make your project talk to the Internet? Connect your existing project to the Internet to log, stream, and interact with the data it produces? What about all this Internet-of-Things (IoT) stuff?

Adafruit IO is a platform designed (by us!) to display, respond, and interact with your project's data. We also keep your data private (data feeds are private by default) and secure (we will never sell or give this data away to another company) for you. It's the internet of things - for everyone!

Why We Built Adafruit IO
Here at Adafruit, we sell all of these amazing components, but we couldn't find a good way to interact with them over the Internet. There are certainly a lot of great services out there for datalogging, or communicating with your microcontroller over the web, but these services are either too complicated to get started, or they aren't particularly fun to use. So, we decided to experiment with our own system, and that's Adafruit IO.
