1
00:00:00,720 --> 00:00:08,280
Let's continue with an altitude or high altitude, and this would allow us to grow a message or to send

2
00:00:08,280 --> 00:00:18,070
a message from no rate to the Broca and then would use a subscriber indicative box to display that message.

3
00:00:18,780 --> 00:00:21,270
So let's grab and kick it out.

4
00:00:22,990 --> 00:00:32,900
There is some carry out and we need a note that will allow us to send some a message to immediately

5
00:00:32,920 --> 00:00:33,290
out.

6
00:00:33,310 --> 00:00:37,080
And of course, the best one and the easiest one at least is they inject one.

7
00:00:37,780 --> 00:00:43,870
So connect these two now for the message, I guess for our purposes, the time stamps.

8
00:00:43,880 --> 00:00:52,720
OK, so I'm just going to leave it at that time stamp then and figure it out because that was a name

9
00:00:52,720 --> 00:00:53,260
this time.

10
00:00:55,930 --> 00:00:59,410
And get it out, I would like to.

11
00:01:01,870 --> 00:01:04,170
Published his message to.

12
00:01:06,090 --> 00:01:11,580
This topic and I'm going to be using the market declined on notarised local.

13
00:01:12,690 --> 00:01:13,420
Quality service.

14
00:01:13,440 --> 00:01:14,250
Just leave it at zero.

15
00:01:14,790 --> 00:01:17,760
All right, done and deploy.

16
00:01:18,660 --> 00:01:20,180
Let's go over to the other side now.

17
00:01:20,190 --> 00:01:27,950
I'm going to add a subscriber and I want the subscriber to subscribe to this topic.

18
00:01:30,760 --> 00:01:32,500
And subscribe.

19
00:01:32,770 --> 00:01:40,420
All right, I'm going to click on the button to trigger the inject node, and there's the message coming

20
00:01:40,420 --> 00:01:40,720
through.

21
00:01:45,490 --> 00:01:51,970
Easy so you can see there's nothing to it is really, really simple instead of a time stamp.

22
00:01:52,000 --> 00:01:57,310
Of course I can just have a regular string A, B, C.

23
00:01:59,100 --> 00:02:07,620
Deploy that trigger and this ABC coming through, or as you know by now, very much any text based payload

24
00:02:07,980 --> 00:02:08,920
is possible.

25
00:02:09,660 --> 00:02:20,640
So let's take the entity in and get it out knowledge and know how to the next step now where I'm going

26
00:02:20,640 --> 00:02:29,670
to be publishing and subscribing to topics that relate to that are posted by the DHT 22 sensor that

27
00:02:29,670 --> 00:02:37,140
is already attached to my Raspberry Pi and have a look at some interesting flows that also include dashboard

28
00:02:37,140 --> 00:02:37,740
widgets.
