Let's continue with an altitude or high altitude, and this would allow us to grow a message or to send
a message from no rate to the Broca and then would use a subscriber indicative box to display that message.
So let's grab and kick it out.
There is some carry out and we need a note that will allow us to send some a message to immediately
out.
And of course, the best one and the easiest one at least is they inject one.
So connect these two now for the message, I guess for our purposes, the time stamps.
OK, so I'm just going to leave it at that time stamp then and figure it out because that was a name
this time.
And get it out, I would like to.
Published his message to.
This topic and I'm going to be using the market declined on notarised local.
Quality service.
Just leave it at zero.
All right, done and deploy.
Let's go over to the other side now.
I'm going to add a subscriber and I want the subscriber to subscribe to this topic.
And subscribe.
All right, I'm going to click on the button to trigger the inject node, and there's the message coming
through.
Easy so you can see there's nothing to it is really, really simple instead of a time stamp.
Of course I can just have a regular string A, B, C.
Deploy that trigger and this ABC coming through, or as you know by now, very much any text based payload
is possible.
So let's take the entity in and get it out knowledge and know how to the next step now where I'm going
to be publishing and subscribing to topics that relate to that are posted by the DHT 22 sensor that
is already attached to my Raspberry Pi and have a look at some interesting flows that also include dashboard
widgets.
