1 00:00:00,540 --> 00:00:09,450 OK, so cut the respirator operating system on this hasty cut, I'm going to insert it into my Raspberry 2 00:00:09,450 --> 00:00:09,870 Pi, 3 00:00:13,710 --> 00:00:16,530 then the connect and it would table. 4 00:00:20,820 --> 00:00:23,250 And finally, USV Petroff. 5 00:00:28,490 --> 00:00:37,040 All right, you got the power and the disk activity, the green light is blinking, showing that the 6 00:00:37,040 --> 00:00:38,890 Raspberry Pi is beating. 7 00:00:39,260 --> 00:00:44,930 So I'm going to now go over to my computer and log in using SNH. 8 00:00:48,110 --> 00:00:55,130 So it's been a few minutes, a couple of minutes since I applied power to my Raspberry Pi, so the process 9 00:00:55,130 --> 00:01:02,540 has completed and what I'll do is I'll use a utility like this one subnetwork scanner, or you can potentially 10 00:01:02,540 --> 00:01:06,500 use the administration panel of your router. 11 00:01:06,710 --> 00:01:15,230 And the objective here is to find the IP address that your network has given the HP server has given 12 00:01:15,230 --> 00:01:16,900 to your Raspberry Pi. 13 00:01:17,330 --> 00:01:22,970 Can you use my network scanner here and click on scan to look for new devices that were just added to 14 00:01:22,970 --> 00:01:23,660 the network? 15 00:01:24,200 --> 00:01:29,780 Because at this point I can only log in using a stage via the IP address. 16 00:01:30,650 --> 00:01:41,000 So here is an existing Raspberry Pi that is on my network RPI three and this one here is my new Raspberry 17 00:01:41,000 --> 00:01:41,470 Pi. 18 00:01:41,540 --> 00:01:43,940 So at 17 address. 19 00:01:44,450 --> 00:01:48,200 This is the address of my new recipe and I'm going to use it to login. 20 00:01:48,800 --> 00:01:52,700 So SSA is already running, so I'm going to use SSA to log in. 21 00:01:53,300 --> 00:01:59,750 The default username is PI and the IP address. 22 00:02:01,140 --> 00:02:04,800 It's the same one as I'm getting it from the network scanner. 23 00:02:07,040 --> 00:02:07,390 Right. 24 00:02:08,540 --> 00:02:15,260 So this new device or yes, I am sure I want to continue and the default password is Rasberry. 25 00:02:17,820 --> 00:02:18,220 Right. 26 00:02:18,300 --> 00:02:24,300 So I'm logged in now what I want to do is because I don't want to have to remember this IP address to 27 00:02:24,300 --> 00:02:27,500 log in to the Raspberry Pi. 28 00:02:27,520 --> 00:02:33,570 So I'm going to set a hostname and then I'm going to be using the hostname to log in tomorrow, sweetie 29 00:02:33,570 --> 00:02:33,890 pie. 30 00:02:34,380 --> 00:02:43,440 So I'll put the scanner away and enlarge the terminal window a little and I'm going to run the recipe. 31 00:02:45,320 --> 00:02:51,480 Recipe, config, utility, not right, here's a couple of things that we'll do here. 32 00:02:51,770 --> 00:02:56,480 First of all, you can go into network options and change the hostname. 33 00:02:57,880 --> 00:03:05,470 Let's give it a reasonable name such as Noad Red Dot local, right? 34 00:03:05,530 --> 00:03:07,660 So this is going to be the name of this device. 35 00:03:08,250 --> 00:03:11,230 Another thing that I want to do is. 36 00:03:12,720 --> 00:03:18,240 And perhaps to go to advanced options and expand to filesystem. 37 00:03:18,270 --> 00:03:19,020 That's one thing. 38 00:03:20,970 --> 00:03:26,920 Don, I'm going to have to do a reboot for this and then finally back into advanced options. 39 00:03:27,540 --> 00:03:34,380 I want to allocate less memory, let's say just two megabytes to the CPU, since we're not going to 40 00:03:34,380 --> 00:03:36,520 be using any CPU at all. 41 00:03:37,080 --> 00:03:44,550 I prefer to keep the full amount of 256 megabytes of RAM for my applications to use. 42 00:03:44,790 --> 00:03:45,380 All right. 43 00:03:45,780 --> 00:03:46,260 That's it. 44 00:03:47,070 --> 00:03:50,460 Now it's going to finish and reboot. 45 00:03:51,840 --> 00:03:57,300 So I'm going to give my Raspberry Pi another couple of minutes to finish rebooting. 46 00:03:57,300 --> 00:04:01,020 And the next time I login, it will be with the hostname. 47 00:04:02,110 --> 00:04:03,010 Let's try this out. 48 00:04:03,030 --> 00:04:04,820 So this is how much? 49 00:04:07,980 --> 00:04:18,570 The U.S. pay and now note read local is the hostname of my Raspberry Pi report, found it locked in 50 00:04:19,560 --> 00:04:21,030 with his name Respray. 51 00:04:22,770 --> 00:04:30,840 And if you use the command hostname, you can confirm that the allocated or the assigned hostname for 52 00:04:30,840 --> 00:04:33,330 this record player is not redcoat local. 53 00:04:34,110 --> 00:04:40,440 So now we've got our Raspberry Pi ready for our project will go straight into the next section where 54 00:04:40,710 --> 00:04:47,160 I'll show you how to install and configure node red and then walk through some of its most important 55 00:04:47,160 --> 00:04:50,010 nodes and show you how to create some simple fluke's.
