Blynk

Blynk is a free IoT platform. Let's set up Blynk step by step.

Step 1: Open play store, search for the app Blynk and install the app.

Step 2: Install the app in your device.

Step 3: Find the app icon looks like the one shown below. Then open it.

Step 4: If you have an account log in otherwise click on Create New Account. You can log in using your Facebook account also.

Step 5: Enter your email id and then create a password and enter it. Note that this is not your email id's password. You have to create a different password.

Step 6: Click Sign Up

Step 7: Read the note and Click on Cool! Got it. This service is not totally free but partially free. We will discuss it later.

Step 8: Now its time to make a new project. Click on New Project.

Step 9: Click Project Name to edit it and give it a new name.

Step 10: In my case, I've chosen Test Project.

Step 11: Then Click the drop-down menu and find the controller you are using and select OK. In my case, I have chosen NodeMCU because in my last blog was about programming NodeMCU.

Step 12: Select Connection Type as Wi-Fi and click Create.

Step 13: Click ok and find the Auth token from your email id. We will discuss this Auth Token and how to use it in our next blog. 

Step 14: This is a blank project. Now you have to add some widgets. Now, these widgets are not free. You get only 2000 Units of energy and this energy you have spent to get a widget. The declaration in Step 7 was about this.

Step 15: There are various types of widgets and all have prise. So choose your weapon wisely.

I'll discuss some of these widgets later in another blog.
