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 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 …).

FriendlyElec has released a $35 rival to the Raspberry Pi 3 B+, outdoing the better-known board with 2GB of memory, Gigabit Ethernet, and a more powerful GPU.

The NanoPi K1 Plus follows FriendlyElec's Nano Pi K2, released last year with similar dimensions to the Raspberry Pi 3 for $40.

The NanoPi K1 Plus shares similar specs to the Nano Pi K2 and maintains the Raspberry Pi's form factor, but offers double the RAM, Gigabit Ethernet, and 4K video playback.

The device also has the same 40-pin GPIO pin-header as the Raspberry Pi 3, so it should work with Raspberry Pi accessories and housings.

Instead of the NanoPi K2's 1.5GHz Amlogic processor, FriendlyElec opted for an Allwinner H5 quad-core 64-bit Cortex A53 processor that runs at 1.4 GHz as well as a six-core Mali450 GPU. The Raspberry Pi 3 B+ uses a 1.4GHz Broadcom BCM2837B0, Cortex-A53 ArmV8 64-bit SoC.

The NanoPi K1 features three USB 2.0 ports, one microUSB 2.0 port for power, a microSD slot, while wireless support includes 802.11 b/g/n.

Mettre en place un réseau WI-FI privé n’est pas toujours nécessaire quand vous êtes chez vous bien au chaud à proximité de votre Box et que votre activité numérique consiste principalement à consulter vos mails ou à surfer sur le net mais dans certains cas, cela peut s’avérer très utile. Prenons l’exemple de la domotique qui intéresse de plus en plus de personnes et qui permet de contrôler vos différents appareils électriques à l’aide d’une seule télécommande (ou de votre téléphone) via votre réseau. Dites vous bien que tous ces appareils doivent bien communiquer entre eux et que, dans l’idéal, une connexion sécurisée serait un plus indéniable.

Step by step tutorial on how to export projects from Blynk into your own apps that will work with any connected product you build.

ESP8266 WiFi Weather Station with Color TFT Display We were playing around already with LED MATRIX's, devices to visualize measured values and/or texts. In this blog post (Tutorial) we will use a TFT Display (Thin-film-transistor liquid-crystal display) with touch screen to display a three (3) days weather forecast with moon phases. This…
