To easily understand IoT through Blynk Platform



Let’s imagine a normal life routine. A family is ready to go on a picnic over the weekend on a beautiful day. Father is checking the tent in the garden and mother is preparing food. Children are so excited about the picnic as it has been a while. On their way to the picnic, father remembers that he forgot to lock the front door and mother thinks that she forgot to close the gas valve, and children think that they forgot to feed their parrot. They cannot return home right now but if they can remotely check the status of the front door, gas valve, and their parrot, they will be able to have a comfortable picnic.

What is IoT?

IoT is the concept of network connectivity. According to Wikipedia, the internet of things (IoT) is the network of physical devices, vehicles, buildings and other items—embedded with electronics, software, sensors, and network connectivity that enables these objects to collect and exchange data. IoT enables device data to exchange through network and if the user analyses it, IoT will be able to provide customized service to the user.

Typical example of this service is home IoT service provided by mobile-service companies. You can better understand what kind of service is provided by watching the videos below.

What is Blynk Platform?

We can use the Blynk Platform to beter understand the concept of IoT. Since many parts of the IoT service are connected with a smartphone, we can improve the understanding of IoT by using a free smartphone application called Blynk. Blynk is a typical smartphone application that was crowd-funded via Kickstarter. Users can easily make Widget and remotely control embedded devices such as Arduino. For more information, please refer to the following video.

The following website provides tutorials on how to control IoT devices using Blynk; it will be helpful since it includes SW & HW information required for actual implementation.

Getting started with Blynk and Arduino. Switch the lights ON over the Internet

This project shows a simple home automation demo built with an Ethernet shield and relay module. Users can control lights with Arduino using Blynk.


This is the most common Blynk example that shows how to turn on and off the relay connected to the device by controlling GPIO pin of Blynk application. This also shows that it is possible to manage home lighting.


Rain Waring Display on Mobile for your Home Garden

This is a system that notifies users about unexpected raining to help out their gardening. The system displays real time values on mobile.


Users can check the value by connecting the sensor to an IoT device. Basic structure capable of monitoring the data remotely and connecting the desired sensor is explained.


Smart Parking

A system that informs you about the available parking slots of an area.


People can check the parking validation service configuration that is used currently; userss can check the value of sensor on the server or smartphones.
