WEBVTT 00:00.050 --> 00:02.720 What is the Raspberry Pi and what can you do with it? 00:02.750 --> 00:08.960 The Raspberry Pi is a very small computer, almost the size of a credit card, but it is quite powerful 00:08.960 --> 00:11.030 and it can run a lot of applications. 00:11.060 --> 00:13.040 So what can you do with this board? 00:13.070 --> 00:17.210 Here are some examples of projects that you can easily do with a Raspberry Pi. 00:17.240 --> 00:23.780 You could automate your home, make your personal devices smarter with IoT or Internet of Things. 00:23.780 --> 00:31.280 You can also build a retro gaming console, create a security on alarm system, host a server for a 00:31.280 --> 00:32.900 web or mobile application. 00:32.900 --> 00:36.140 You can even run a minecraft server on your Pi. 00:36.170 --> 00:42.740 You can also program robots such as robotic arms, drones, hexapods, mobile robots, etc. you can 00:42.740 --> 00:48.860 create a smart mirror, install different operating systems, for example Raspberry Pi OS, ubuntu, 00:48.890 --> 00:51.110 windows IoT and much more. 00:51.140 --> 00:54.890 Or simply use the Raspberry Pi as your own portable computer. 00:54.890 --> 00:58.250 And of course, this list is far from being exhaustive. 00:58.280 --> 01:04.760 You can find many more projects online, and you can also get inspired to create your own custom projects. 01:04.760 --> 01:08.720 One great thing about Raspberry Pi is the community. 01:08.720 --> 01:11.570 So what does the community aspect bring to you? 01:11.600 --> 01:15.440 Well, you can easily see what other people do with their Raspberry Pi. 01:15.470 --> 01:21.020 You can ask your questions, get some help from more advanced users, and you can also collaborate with 01:21.020 --> 01:24.740 other people on similar projects and progress together. 01:25.010 --> 01:28.340 Raspberry Pi was created by the Raspberry Pi Foundation. 01:28.340 --> 01:34.340 The goal of the foundation is to make computers and digital making available for as many people as possible. 01:34.340 --> 01:39.650 For about 50 USD, you can get a Raspberry Pi board and a complete setup to run. 01:39.650 --> 01:41.960 It would not be that much more expensive. 01:41.960 --> 01:45.170 Now let's talk about the different versions that you can find. 01:45.200 --> 01:48.980 The first Raspberry Pi board was released in 2012. 01:49.010 --> 01:55.850 Then the foundation continued to develop new iterations to make the board more powerful, add more functionalities, 01:55.850 --> 01:59.030 make it easier to use and develop the community. 01:59.060 --> 02:05.180 In 2015, the Raspberry Pi two was released with much more computation power than the first one. 02:05.180 --> 02:11.990 Then the Raspberry Pi three came in 2016 with again more computation power, and this time the WiFi 02:12.020 --> 02:18.580 feature was directly integrated inside the board, so you don't have to use the Wi-Fi USB dongle anymore. 02:18.610 --> 02:22.120 In 2019, the Raspberry Pi four was released. 02:22.150 --> 02:24.310 Better performance than the version three. 02:24.340 --> 02:30.610 A few changes in the external connectors to make it compatible with modern applications, and an increased 02:30.610 --> 02:31.510 amount of Ram. 02:31.540 --> 02:36.130 And finally, we have the Raspberry Pi five released in 2023. 02:36.160 --> 02:38.770 Twice as powerful as the version four. 02:38.800 --> 02:45.070 An additional fan and camera connectors, and a few differences in the architecture that makes it even 02:45.070 --> 02:45.640 better. 02:45.670 --> 02:51.970 The Raspberry Pi boards up to version three only had one gigabyte of Ram, which was already quite good 02:51.970 --> 02:52.630 at the time. 02:52.660 --> 02:58.210 Now for the Raspberry Pi four and five, you can choose between two gigabytes, four gigabytes, and 02:58.210 --> 03:02.080 even eight gigabytes of Ram, which is becoming quite huge. 03:02.110 --> 03:04.930 Now what can you find on the board? 03:04.930 --> 03:07.450 So in the middle you can see lots of components. 03:07.450 --> 03:14.140 Those are the CPU, the Ram, the Wi-Fi and Bluetooth chips, and all other components required to make 03:14.140 --> 03:15.400 the Raspberry Pi work. 03:15.430 --> 03:17.560 Now let's focus on the connectors. 03:17.590 --> 03:25.030 You have four USB ports, including two USB, three in blue, one Ethernet port with Gigabit Ethernet, 03:25.030 --> 03:33.280 one USB-C port to power on the board, two micro HDMI ports with 4K video support for two external displays. 03:33.280 --> 03:40.960 You also have two ports that can be used for either a camera or a display module, a PCI port, a 40 03:40.990 --> 03:47.140 pins or Gpio header that we will use a lot during this course to control different hardware components. 03:47.140 --> 03:52.000 With Python programming, Gpio means general purpose input output. 03:52.000 --> 03:57.850 This header is the same for the Raspberry Pi to be three B Raspberry Pi four and Raspberry Pi five. 03:57.880 --> 04:03.490 You also have one fan connector here, which is new on Raspberry Pi five, and I'm going to finish with 04:03.490 --> 04:09.310 the back here with a slot for the microSD card in which you will install the operating system. 04:09.310 --> 04:14.770 All right, now you should have a slightly better idea of what the Raspberry Pi is, what is its purpose, 04:14.770 --> 04:16.960 and the applications you can do with it. 04:16.990 --> 04:22.690 When learning about a new technology, it's always a good idea to try to understand the big picture 04:22.720 --> 04:25.150 first, and now we can dive in.
