Learn – Blynk the IoT App
Do you want to make your IoT project? Stay with us and follow this Tutorial! We will explain you what is Blynk and how to make your first Iot project with it!
Blynk is an app that makes it very simple to make IoT projects using the most known boards. (Such as WeMos D1, WeMos D1 mini, NodeMCU and a lot more…)
Moreover it’s free, but you can pay to have more features, anyway the free plan is enough for simple projects.
With this app you will use your smartphone to control your Wi-Fi board.
Let’s talk more about it!
Create a free Account
- Then press on “New Project”
- Now you have to choose a name, select your device and the connection type.
- Then press on Create, it will create your first Project and will send to your email a code called Token.
- Then you have to choose your Widget.
There a lot of widgets, but as free plan we can use only 1400 points. Each widget has a cost. Of course you can pay to get more points.
Anyway they will be enough for simple projects!
How to Setup an Arduino Sketch
We have to setup the arduino code to be configured with our Blynk App.
First of all add the Blynk library. If you don’t know how to add a library to arduino IDE follow our guide.
Then go in file/exemples/BlynkBoards_WiFi/ESP8266_Standalone
This is the example:
So get the Token from your email (they will send it when you create a new Blynk project).
You have to put it where there is written “YourAuthToken“
Change the name to “YourNetworkName” and write your password for your Network instead of “YourPassword“.
We will make some projects and we will write also some sketches, but not in this article!
