Add Datastream

For the goal of this tutorial skip the Metadata Tab and go directly to Datastreams tab in your Template.

Datastreams are channels that are used to send data between the device and Blynk.Cloud. We will be using this Datastream to send random values from your device.

Click on Add Datastream button. Choose Virtual Pin in the dropdown menu:

Set up the Datastream like this:

  • Name: Random Value Send

  • Virtual Pin: V0

  • Data Type: Integer

  • Min/Max: 0/100

Skip all the other settings. When done, press Create and the new Datastream will be created.

These settings mean that all the devices that inherit this Template will process integers in the range of 0 to 100 through a Virtual Pin V0

Add a Second Datastream

Click on Add Datastream button again. Choose Enumerable type in the dropdown menu and set up the Datastream. We will be using this Datastream to send a value from mobile and web dashboards to the device.

  • Name: Button

  • Virtual Pin: V1

  • Add Row1: 0, OFF

  • Add Row2: 1, ON

Skip all the other settings and press Create

These settings mean that all devices that inherit this Template will process values integers in the range of 0 to 1 through a Virtual Pin V1and Blynk will interpret 0 as OFF and 1 as ON strings.
