1 00:00:00,720 --> 00:00:06,300 In this lecture, I'll talk about the software requirements of this project, course, all of the software 2 00:00:06,300 --> 00:00:12,810 that were used in this project is open source and free in terms of monetary cost, online services like 3 00:00:12,810 --> 00:00:17,070 Google Sheets and efficient that are also free of charge, but not open source. 4 00:00:17,380 --> 00:00:18,620 So let's take a closer look. 5 00:00:20,230 --> 00:00:26,680 The software component that consists of the brain of the project is not read, not read is a powerful 6 00:00:26,680 --> 00:00:28,410 graphical programming environment. 7 00:00:28,810 --> 00:00:36,400 It's built on note JSA JavaScript framework from where it got its name not read is very good in enabling 8 00:00:36,400 --> 00:00:42,520 hardware devices, small and large APIs and all kinds of online services to work together. 9 00:00:43,510 --> 00:00:49,540 Note read is bundled in the European operating system, even in the light version that will be using. 10 00:00:49,820 --> 00:00:55,870 However, I'll show you how to install a fresh copy so that you can start the project with the latest 11 00:00:55,870 --> 00:01:02,680 available version, although will be using the E.S.P 32 to implement the hardware part of the terrarium 12 00:01:02,680 --> 00:01:03,280 controller. 13 00:01:03,580 --> 00:01:07,990 I've decided to use the original idea as a development environment for the sketch. 14 00:01:08,590 --> 00:01:15,280 I chose this as opposed to platform IO that are used in my course SB 32 unleashed because the sketch 15 00:01:15,280 --> 00:01:17,370 that will develop is actually fairly simple. 16 00:01:18,010 --> 00:01:23,980 The original idea is perfectly suitable and capable for what we are working towards here, and it's 17 00:01:23,980 --> 00:01:31,780 definitely allowing us to progress at a faster pace as opposed to using a more feature for ADT to keep 18 00:01:31,780 --> 00:01:33,070 a fast pace. 19 00:01:33,220 --> 00:01:37,870 I'm not showing how to set up the original idea to work with the ISP 32. 20 00:01:38,260 --> 00:01:45,970 It can learn how to do this by reviewing the relevant lectures in E.S.P 32 for people, or check out 21 00:01:45,970 --> 00:01:49,630 the relevant free guide on the Tech Expression's website. 22 00:01:49,780 --> 00:01:54,070 And you can see the real for that guide below the image in this slide. 23 00:01:56,430 --> 00:02:02,670 The default operating system for the Raspberry Pi is the Raspberry Pi OS, this used to be known as 24 00:02:02,670 --> 00:02:04,060 Rampion until recently. 25 00:02:04,710 --> 00:02:10,080 We won't be doing much at the operating system level other than running the necessary services such 26 00:02:10,080 --> 00:02:13,930 as S h note rate and the T Muskett a broker. 27 00:02:14,340 --> 00:02:18,720 I'll show you how to install the operating system and set up those services. 28 00:02:19,970 --> 00:02:27,290 Notarised is the brain of our terrorism controller, and quiddity is the glue and quiddity makes it 29 00:02:27,290 --> 00:02:30,930 possible for this software components to communicate with each other. 30 00:02:31,580 --> 00:02:33,860 Eclipse Miskito is an open source. 31 00:02:33,860 --> 00:02:41,180 Epel and IDEO licensed Message Broca that implement the EMCDDA protocol versions five three point one 32 00:02:41,180 --> 00:02:49,070 point one and three point one mosquito is lightweight and is suitable for use on all devices from low 33 00:02:49,070 --> 00:02:56,150 power, single board computers to full service and quiddity is a way of messaging that allows clients 34 00:02:56,150 --> 00:02:59,850 to talk to each other using the public and subscribe model. 35 00:03:01,070 --> 00:03:06,170 Of course, there are many open source implementations of the military protocol and any of them should 36 00:03:06,170 --> 00:03:08,100 work equally well in this project. 37 00:03:08,270 --> 00:03:14,240 There are no specific requirements that we have here that makes mosquito better than other options. 38 00:03:14,750 --> 00:03:20,930 But in this project I have chosen to use the Mosquito Breuker because it's well documented and mature 39 00:03:21,080 --> 00:03:25,730 and also comes with convenient publish and subscribed tools that we can use for testing. 40 00:03:25,910 --> 00:03:27,790 Apart from the broker itself. 41 00:03:29,980 --> 00:03:36,500 To make this project a true Iot project, I decided to make use of online cloud resources and services. 42 00:03:37,090 --> 00:03:38,830 There are many excellent options out there. 43 00:03:38,840 --> 00:03:43,780 So I wanted to make use of services that are genuine representatives of what is available to make us 44 00:03:43,780 --> 00:03:44,190 today. 45 00:03:45,400 --> 00:03:51,310 Most such services are not open source, but are free of charge, at least at a basic level, which 46 00:03:51,310 --> 00:03:51,980 is all we need. 47 00:03:52,810 --> 00:03:56,270 The first cloud application that I wanted to use is Google Sheets. 48 00:03:56,860 --> 00:04:03,730 It's possible to use Google Sheets via a specialized API because al Qaeda is integrated with Google 49 00:04:03,730 --> 00:04:04,370 Drive. 50 00:04:04,390 --> 00:04:07,780 We also need to make use of the Good Drive API. 51 00:04:08,410 --> 00:04:14,770 The main challenge to use Google Sheet is the security and authentication mechanism, which requires 52 00:04:14,770 --> 00:04:17,590 the creation of certificates and keys. 53 00:04:18,430 --> 00:04:23,350 This is a common and very secure way to getting access to online resources. 54 00:04:23,350 --> 00:04:25,390 And I'll show you exactly how to do this. 55 00:04:26,470 --> 00:04:31,120 Will use Google Sheet to log data from the terrorism controller, sensors and actuators. 56 00:04:31,390 --> 00:04:36,370 But you can use the same techniques to access any of the many other Google services. 57 00:04:37,920 --> 00:04:44,370 If this and that is the leading platform for bringing together hundreds of registered services and using 58 00:04:44,370 --> 00:04:50,370 them in virtually any way you want, I'll be using if this and that to send me notifications when the 59 00:04:50,370 --> 00:04:54,890 voltage level of the ISP 32 battery drops below a certain threshold. 60 00:04:55,290 --> 00:04:57,590 But that is just one simple example. 61 00:04:58,170 --> 00:04:59,050 It can do much more. 62 00:04:59,430 --> 00:05:05,130 For example, you can use if they send that to automatically make an entry in your calendar to remind 63 00:05:05,130 --> 00:05:12,450 you to charge the terrorism battery or to replenish the water reservoir, it can use Amazon, Alexa 64 00:05:12,570 --> 00:05:14,650 to set up voice commands or alerts. 65 00:05:14,650 --> 00:05:16,490 And that's just scratching the surface. 66 00:05:17,340 --> 00:05:19,060 If this and that is an amazing tool. 67 00:05:19,170 --> 00:05:24,330 And in this project, I'll show you how to easily integrate it to your no red flow. 68 00:05:25,540 --> 00:05:30,400 As with Google services, if this and that is not open source, but you can use it free of charge. 69 00:05:32,570 --> 00:05:37,130 There are various other software components that will use in this project, for example, there are 70 00:05:37,130 --> 00:05:43,010 libraries for the Espiritu and they are doing your I.D., such as the Task Scheduler Library, which 71 00:05:43,010 --> 00:05:48,230 allows us to schedule specific things to happen on the ESB 32 that follow a specific schedule. 72 00:05:48,860 --> 00:05:53,930 There are also note, read, note libraries that will be installing and using. 73 00:05:54,590 --> 00:06:00,230 As with the Ardino, there are thousands of contributors who have written thousands of note, read notes 74 00:06:00,230 --> 00:06:02,000 and even complete flows. 75 00:06:02,000 --> 00:06:08,360 And they are sharing those with other makers so that we can integrate them to our projects and it's 76 00:06:08,360 --> 00:06:08,780 about it. 77 00:06:09,230 --> 00:06:13,460 Now let's move on to the next lecture of talk about the required hardware.
