## Article

There are three major components in the platform:

- Blynk App – allows to you create amazing interfaces for your projects using various widgets we provide.

- Blynk Server – responsible for all the communications between the smartphone and hardware. You can use our Blynk Cloud or run your [private Blynk](http://docs.blynk.cc/#blynk-server) server locally. It’s open-source, could easily handle thousands of devices and can even be launched on a Raspberry Pi.

- Blynk Libraries – for all the popular hardware platforms – enable communication with the server and process all the incoming and outcoming commands.

INTRODUCTION OF ARDUINO ETHERNET SHIELD W5100

![](https://maker.wiznet.io/upload/ckeditor5/713610564%5F1676066646%2Epng)

The **Arduino Wiznet Ethernet W5100 Shield** allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 ethernet chip providing a network (IP) stack capable of both TCP and UDP. The Arduino Ethernet Shield supports up to four simultaneous socket connections. Use the [Ethernet library](http://arduino.cc/en/Reference/Ethernet) to write sketches which connect to the internet using the shield.
