Yes, hello and welcome to a new technique All video. Today, everything revolves around single board computers with a little development calculations that are built on a single circuit board. I have brought three different platforms with me for you and will show you them strengths and the differences between the individual systems in detail off. We go with respect. Most of you are allowed to raspberry. Pi have been on the market for eight years now and now here in the fourth generation has made this platform a really powerful platform integrated with a quad core processor now built in 1 5 Gigahertz computing power and four gigabytes of Ram. Do the rest Ericsson. About real powerful computers and how to get on with the finish of the Circuit Board does not see that with a self-soldered circuit board. Really something to do here. We have everything connected the heart desires. We have us PC. We have two HDMI ports, one audio output USB 20 USB 3.0 expected. We have Bluetooth and wlan on board and with it, we have really reduced a computer to the essentials and precisely that makes the rest of the Barry P for Web applications or for applications where I am. The graphic skills would like to use so interesting. Many use the best Mary couple. Yes, also as a media center because he H 264 and now hair 265 as codec can massively accelerate and now in the fourth generation, even 4k can play videos. That means I can watch them as streaming box on when I find. I want to turn on my big computer. I can use it to control. Displays, for example, like in the Konrad Smart Miro project was already implemented to get data from the Internet, such as showing weather data on a display or in one shop window always wants to present something when an Internet and Graphical data come together, and I get a certain number for it computing power or maybe a small web server. What you want, then the Raspberry Pi is my single board computer of choice. The next one in the row is here the Arduino or here, specifically, the Arduino Bruno, we have a slot mega 328 microprocessor on it 20 megahertz computing, power, two kilobytes of working memory and 32 GB flash memory. The ADU is really for tinkering and developing close to hardware thought there is also around the ruin or pretty large community, so that me there are many sketches that are so source code snippets can already be downloaded and all they have to do is adapt for my own projects. That is me in many parts. I don’t even need the software. One hundred percent myself develop. You can fall back on the community me. Just download large parts. That fits mine. A bit application to so much work of the language can come to mine so faster. Aim, also in the focus of the aroon is the expandability. First there is a deficit executed the pins. Once here, the digital pins around to capture digital signals, I just have outputs to motors or Leds R to be able to control as well as analog inputs and outputs to detect sensors or something about it and taxes and corresponding expansion of the sport reduced. For example once. I brought the motor ship with me. I can use it control. Two pwm-controlled motors directly That is simply put on top of it is also now in size from above completely identical, And so I have the direct opportunity to be powerful to control hardware about it and through which I can contact all my sensors or other interfaces continue to do the same retained and precisely because it is very much for hardware tinkering and developing is thought there is also something like proto boards. That is now just here. A blank circuit board is probably not much more on it than that connections for my reports, however, the UCI boss and that can also simply be above stuck on it and can build a completely separate circuit on it. If I do wants to have, it solved a bit nicer than just the individual now access interfaces and build up the rectorate on a wakeboard. So you notice Arduino? It was just something for all those who liked it themselves develop or just take the soldering iron in hand and do it yourself switching to answer the latest development platform Beer in the round. Is the reception stick. M5 simply stands for modules 5 cm because the whole 5 cm tall and stackable. The m56 itself is like one already looks a relatively mature finished development sports that is we will already have a closed housing and a relatively large one functional scope In the basic version with steps we have an LCD screen with 320 x 240 pixels. We have a speaker, we have a microphone. There is a new axis to detect movement to the office example as a pedometer. We have an SD card reader and we still have the option as with Arduino on the individual pins to access to give analog digital ports to use with, it led together control in order to realize switching and also has hardware to tinker it. You close the gap between the Raspberry Pi and the Arduino because its range of functions also works with Bluetooth and Can come up with Wifi but is still very hard when built like that that we still have access to everything here. The expandability is relatively important, also when receiving there are then just the finished modules, which I now here as an add-on like the proto here. But I also switch it build your own circuit can simply expand here. They will simply have put theirs in the bar with them. Ports are passed on, and then there is stop afterwards as a conclusion. Our bot template and then. I have the reception at one functional level. In addition, there are also completely external sensors that are then over pit stopped this connection or in the maintenance version. That is the one red fire edition connected to the ports. So there is another already finished sensor like humidity sensors, camera sensor heat sensor directly via a connecting cables can be the focus of the m5 platform. So more on software development. I can really focus on it here. Concentrate sensors to read something to control the whole thing, maybe to represent graphically and to make the entry into the level. What do I do when I press the keys? How can I evaluate everything that can I deal with it and just present it to me in the media? I am now here for you. A brief table 1 with the essentials technical data of the three platforms in comparison. If you take your time read through Volt positive, a short video. Who is now which platform is the most suitable one? Of course that can be done in the detail does not give a general answer to the transitions between the individual. Platforms are also relatively fluid, But I’ll still try roughly in to give order as it is from my point of view. In my opinion, the Raspberry Pi is the right platform for everything requires online access and what a certain powerful hardware presupposes that I can set up a media center on the rest of the way Can that use video streaming? I can use an FTP server. Set up! I can use this as a webmail clienti and I can with it. Everything that a normal computer can do in a small and dedicated way, for example. I can also use the pin bar here to have a small. Disadvantage of the led building. If I always get an e-mail or or or there are many applications always when there is internet and hardware. Then it is the right platform for the raspberry. Pi Arduino, on the other hand, relies entirely on hardware development. We have come from here. Plant a network interface on board, but this is really about it to develop things hardware, ie that is suitable for all developers who who want to build their own circuit and who want to take their first steps in the want to go to the microprocessor world And then see, how can I get one of my own? Connect the circuit to the Wii controller. How can I possibly do? Something expand an existing one by 1 mio controller or how can. I add a replace or improve previous circuit with a controller That means we do a lot of tinkering with extensions such as tinkering with Stepper Motors with Leds with displays but always hardware and that means something for all those who like to build something themselves with the soldering iron squares and just have fun with direct dedicated tinkering, The m50, on the other hand is aimed more at school classes or AGS or people who want to deal less with the hardware itself, but rather with the software development around the hardware that is software develops. That is very, very close to the sensors or do not want to connect to the functions. But how you do. I see a closed case here. And there is far less hardware. Lanci, as held in Haguenau. For example, that means I can just do it here. Connect Ready-made solutions. Be it a sensor. Be it a keyboard, be it a motor and I can then focus on the software develop something to graph or like it, yes. The whole thing is already available in many schools, for example to be linked here with a Lego technic setup, so I can then use this vaccination effect to take the first steps, for example to do in robotics without worrying about what is here now. Exactly what hardware is needed, but this platform is already powerful enough to be able to cope with all eventualities so that they can do me. Here you can really concentrate on the programming and on the essentials. That was my little overview of the three single board computers. For me as a hardware hobbyist, the Arduino is the means in most cases the choice but writes mine in the comments, which platform you prefer to use and which projects you already have have implemented the links to the three can be found below in the description. Have fun tinkering and see you in the next video.
