[00:00.000 --> 00:26.560]  Let's just fetch our microblocks here, this happened to me before, why did that go away?
[00:26.880 --> 00:34.480]  I need to, let me just quit microblocks a second, oh there it goes, no I don't want to
[00:34.480 --> 00:41.280]  quit, okay so the cable wasn't quite plugged in, for some reason I lost my displays do something,
[00:41.280 --> 00:48.400]  so I said basic sensors just like that heady language, actually let me just quit microblocks
[00:48.400 --> 00:56.240]  really quick, this cable is being a little flaky, no no no it's and also in the display, okay
[00:56.560 --> 01:02.560]  so this is what it looks like and you have outputs, you have inputs and then you can do all the pins,
[01:02.560 --> 01:08.560]  you have your control variables, operators, all sorts of stuff like that but it, I plugged in
[01:08.560 --> 01:14.480]  this board, it showed a green here, it's already connected so it already knows what this board is
[01:14.480 --> 01:22.640]  and when I click temperature it tells me it's 19 degrees C, if I want to see the display I simply
[01:22.800 --> 01:30.080]  turn on the display, oh let's see I need this quick camera, so for those of you at home
[01:31.520 --> 01:40.880]  there's my happy face and then I click temperature, there it is there, keep losing this connection,
[01:41.600 --> 01:47.280]  okay, all right,
[01:52.160 --> 01:58.240]  every time the HDMI pops in and out it's causing microblocks to be unhappy, sorry about that,
[01:59.840 --> 02:09.040]  what's that, okay all right let's just try this one more time, load microblocks
[02:11.040 --> 02:18.960]  and another particularly cool
[02:21.840 --> 02:35.040]  it's okay, well it's very flaky, oh I lost it, let me see what happened to my power, so HDMI is lost
[02:41.840 --> 03:00.800]  don't touch anything, yeah we might have a few screen issues here, let me just try really quickly
[03:00.800 --> 03:12.080]  if I can quit and open again, okay, quite briefly I wanted to show you that you can
[03:12.080 --> 03:21.840]  graph something like the light level and you can also see the data you know of an input value
[03:22.480 --> 03:33.760]  and it will, let's put zero at the bottom and I can watch this in real time and if I close my hand
[03:33.760 --> 03:41.360]  over it it gets reflections on stuff but so you can see you can plot data in real time x y and z
[03:41.360 --> 03:48.880]  it has an accelerometer, so that's very cool, all right now we're going to go back so that's
[03:48.880 --> 03:56.480]  liveness, there's no compile download it's just happening, next point is that you can do things
[03:56.480 --> 04:05.520]  in parallel, so I'm going to show you a quick how multitasking is handled through just opening the
[04:07.280 --> 04:15.760]  two button blink program right here and I open this and if I press button, let me get my camera
[04:15.760 --> 04:24.480]  okay if I press button A while I'm pressing it it's going to repeat and blink 100 milliseconds
[04:24.480 --> 04:30.880]  while I press B it does the same thing I can actually press A and B and you know I can try to get
[04:30.880 --> 04:36.880]  them in sync or I can try to get them on and off but it's it takes too long so just as Hetty has
[04:36.880 --> 04:43.600]  you know variables I can do something like a delay so I can try to play around with it in real time
[04:44.160 --> 04:55.040]  and I set the delay to like 500 whoops and then I drag this delay variable in so I can play around
[04:55.040 --> 05:05.440]  with a slower blink time and change it all I want while I'm experimenting and now if I set that delay
[05:05.440 --> 05:14.800]  variable you can also use say block so it's it's nice to just set a variable and say it now I know
[05:14.800 --> 05:25.840]  what it is and if I'm pressing the A now you see it's every 500 and I can now I can more like get
[05:25.840 --> 05:32.880]  them on off on off and if you were in an Arduino loop just one continue forever loop this would be
[05:32.880 --> 05:40.800]  a lot harder to have either you know these different sync multitasking done for you which is very
[05:40.800 --> 05:54.080]  very cool the next thing is that it's autonomous so if I am programming and I'm doing these blocks
[05:54.080 --> 06:02.640]  on my my IDE then what happens is there's actually an opcode it looks a bit like assembly language
[06:02.640 --> 06:12.400]  representation of those blocks that our that you can see and then in the actual board it's
[06:14.000 --> 06:22.080]  it's actually in bytecode so if I were to turn on advanced blocks I could show you the instructions
[06:23.040 --> 06:33.040]  and you can see that and then I could actually actually see the bytecode and the bytecode is then
[06:33.040 --> 06:40.000]  what is inside the virtual machine so that will have cool ramifications about sharing our our files
[06:40.000 --> 06:48.240]  when we get to that point okay so um so blocks equate equate to bytecode so it's autonomous in
[06:48.240 --> 06:55.840]  the sense that if I unplug it from my laptop and I plug it back in then
[07:01.120 --> 07:12.160]  what happened did I did I lose my connection okay just oh I know what happened for autonomy
[07:12.160 --> 07:17.840]  I made a mistake I actually need a when started block to set that delay because there was delay of
[07:17.840 --> 07:24.560]  zero right so I actually needed this to be set okay we have to show our errors
[07:26.480 --> 07:42.160]  and now down here so there we go and I love having a co-speaker okay and then another
[07:42.640 --> 07:51.040]  another very awesome aspect of it is its portability so micro blocks if you you look at how we build
[07:51.040 --> 07:57.200]  the virtual machine we have a platform IO script within any file that has I looked last night
[07:57.200 --> 08:03.680]  there were up to 43 different boards and there's a kind of about nine varieties that if you go into
[08:03.680 --> 08:10.880]  micro blocks itself and you want to update the firmware on a board it will show you um well
[08:10.880 --> 08:17.040]  this is plugged in now I'm just updating the firmware on it but uh let me just unplug this for a moment
[08:17.920 --> 08:24.720]  and if you want to update the firmware on a board there's like micro bits calliope city the esp32s
[08:24.720 --> 08:28.400]  there's some new electrophreak the raspberry pi pico's and the eight behind eight of fruit is a
[08:28.400 --> 08:33.280]  whole bunch of boards but there's also in the platform IO any file a whole bunch of Arduino
[08:33.280 --> 08:40.720]  boards and and other stuff that's there so it's it's portable and I want to do a quick
[08:44.000 --> 08:51.680]  display of that where I take this quick cam I'm gonna make it big
[08:54.480 --> 09:00.960]  and we apply power so I have a whole bunch of boards plugged into a usb strip let's hope
[09:00.960 --> 09:06.160]  we don't lose the HDMI and Bernat's gonna turn that on
[09:08.720 --> 09:14.240]  and now you can see I have the heartbeat program running on a whole bunch of different boards
[09:15.920 --> 09:21.840]  so I kind of cheated on a couple boards that are new and didn't have full support like this
[09:21.840 --> 09:27.440]  M bits board but and of course the circuit playground doesn't have the same thing but on
[09:27.520 --> 09:34.000]  some of these OLED displays you can actually use the micro bit type style of display box and it
[09:34.000 --> 09:41.680]  still works and then go around and push the a button on everything so the a buttons turn them
[09:41.680 --> 09:53.360]  all the smiles and whoops dang just just so now they're all happy face and of course if they have
[09:53.440 --> 10:01.680]  B buttons we can go back to our heart and this is the only one that has a side B button
[10:03.120 --> 10:12.080]  voila so as you know like getting used to a programming environment when you pick up a
[10:12.080 --> 10:17.040]  different board do you want to get a different programming environment every time no clearly
[10:17.520 --> 10:25.440]  so portability portability is really cool okay so did I lose it completely
[10:27.200 --> 10:31.600]  all right I'm about to hand this off so that's good
[10:34.160 --> 10:44.320]  all right it's here okay and then the last part to explain is shareability so
[10:47.120 --> 10:57.920]  uh yeah I could do the same program so shareability is there's a few ways to to deal with this
[10:57.920 --> 11:03.520]  let me go in the slide slide show mode because I'm basically wrapped up one is like you can go to
[11:03.520 --> 11:11.440]  the file open save menu with micro blocks um let me just show you in real time here
[11:11.840 --> 11:20.000]  here so you can just go in here and say file you know save file open and then there's uh
[11:21.600 --> 11:27.600]  then there's these other options like encoded in the url so you can say file copy project url
[11:27.600 --> 11:34.880]  to a clipboard and then you can open it you give that url out and we do this you know embed a
[11:34.880 --> 11:40.560]  you just put a hyperlink on some you know documentation and you can open that right in
[11:40.560 --> 11:44.640]  the chrome browser chrome or edge browser support the serial mode you can't unfortunately use
[11:44.640 --> 11:50.560]  firefox i used to work from a zillip okay and then encoded in the picture so our documentation we
[11:50.560 --> 11:56.320]  have pictures on the websites in the wiki in the learn section and the code is actually embedded
[11:56.320 --> 12:02.400]  in the picture so you drag the picture into your chrome browser and or into your ide standalone
[12:02.400 --> 12:08.000]  or chrome browser and it will actually load the code and then the last part is it's shareable
[12:08.000 --> 12:16.320]  by opening from the board and so um i'm going to have for not demonstrate that as we hand off to
[12:17.200 --> 12:20.320]  more cool demo for part two
[12:28.640 --> 12:30.880]  okay can you hear me yes of course again
[12:31.280 --> 12:39.920]  okay so uh yeah we were talking about portability and one of the aspects of portability is not
[12:39.920 --> 12:45.600]  just that the code is portable across boards but the board itself is an example of portability the
[12:45.600 --> 12:54.720]  board is actually uh it contains the program that you are seeing here right uh in any other microcontroller
[12:55.360 --> 13:00.080]  environment once the code is here the code is here and it's it's gone if you've lost your program if
[13:00.080 --> 13:07.760]  you've lost your source the source is gone right uh in micrologs we have a way oops not this mic yeah
[13:07.760 --> 13:15.680]  yeah this microlog sorry uh that's open from board now i mean the browser version we have versions
[13:15.680 --> 13:22.640]  we haven't mentioned that but we have versions for the browser and for mac windows linux and chromebook
[13:22.640 --> 13:28.480]  and raspberry pi etc so we have many platforms that we support this is the browser version
[13:29.040 --> 13:38.480]  and now it says plug in the board and connect and click the usb usb icon to connect so i'll just
[13:39.280 --> 13:46.640]  connect as it said now i select the usb port and now it's actually reading back the code
[13:46.640 --> 13:51.760]  and it's not like we embedded the blocks inside the board it's actually for the i know this is a
[13:51.760 --> 13:58.080]  slightly geekier audience than our usual so we actually have a decompiler that john built in
[13:58.080 --> 14:04.560]  that's inspired in this quick decompiler uh that john also worked on and what it does is it takes
[14:04.560 --> 14:12.400]  these bytecodes and it retranslates them into what we see here right and just to prove that it still
[14:12.400 --> 14:22.560]  works uh it it does and you know we like to joke that micrologs is so portable that we could even
[14:22.560 --> 14:30.080]  port it to a board that does not exist and that's actually a joke but it's true like we have a board
[14:30.080 --> 14:34.720]  that doesn't exist and can't run micrologs since micrologs is vm-based you could compile this vm
[14:34.720 --> 14:42.720]  for something that does not exist that is virtual and that's why we made boardy boardy is a result
[14:42.720 --> 14:48.720]  of the pandemic we were doing online classes and it was really hard to get hardware to kits
[14:49.440 --> 14:56.640]  uh so that was an idea like christine christiane bowie uh my boss and jens and jatka's boss
[14:57.200 --> 15:03.280]  at SAP she got this idea that we needed something virtual so that kids who don't have access to
[15:03.280 --> 15:08.560]  hardware could still at least try micrologs and that's why we made boardy and boardy as you can see
[15:08.560 --> 15:13.200]  can run the same code it's not a simulator that's very important it's not a simulator it's running
[15:13.200 --> 15:19.840]  it's running the exact same vm so it's a virtual board not a simulator it has its own capabilities
[15:19.840 --> 15:26.160]  it has a couple of buttons it has a speaker it has a touch screen it has a file system it can do
[15:27.040 --> 15:34.480]  htdp client operations so it's a different sort of board okay it's yeah right so it does the same
[15:34.480 --> 15:43.680]  things okay uh but you know this is nice but micro blocks was always about physical computing
[15:44.240 --> 15:49.200]  this is nice if you don't have a board that's a good way to get started but our aim was always
[15:49.200 --> 15:55.760]  to teach physical computing to do tangible things in the real world in the physical world so let me
[15:55.760 --> 16:00.560]  show you one thing that you would not be able to do with boardy and that's connecting external
[16:00.560 --> 16:08.800]  sensors to your board so just this funny sensor that I have in here that's an RFID sensor that's
[16:08.800 --> 16:13.200]  technical mama jumbo for the thing that's in your credit card that lets you pay contactlessly
[16:13.200 --> 16:22.640]  or on your subway card or your gym membership card or whatever and I happen to have some of these
[16:22.640 --> 16:35.520]  cards with me as you all do I'm sure so for example yeah and maybe I need yeah I need a cable
[16:37.920 --> 16:41.280]  oops it's physical
[16:45.840 --> 16:50.560]  so this board has a battery but it's dead that's the problems of the physical world as well
[16:51.440 --> 16:53.920]  so I'm connecting an external battery to it
[16:57.840 --> 16:59.760]  okay and now I'm just going to try
[17:02.960 --> 17:10.000]  this has a micro box program in it by the way that I can show later maybe
[17:12.320 --> 17:14.160]  well I'll show it later so
[17:15.040 --> 17:24.400]  okay so I made it so it recognizes this particular card and it plays a tone okay that's interesting
[17:24.400 --> 17:32.400]  let's try another card okay let's try this one okay
[17:32.720 --> 17:34.720]  okay
[17:36.240 --> 17:39.840]  okay cool I'm missing some
[17:42.560 --> 17:48.560]  no wait yes we'll talk later I'll need a special number that comes with it as well
[17:51.200 --> 17:56.480]  let's try with my bank ones and this one as well
[17:56.720 --> 18:04.640]  okay so we have a bunch of cards and we've seen that each of them can make a note let's try to maybe
[18:11.520 --> 18:16.800]  oh yeah where is it I know it's somewhere
[18:19.760 --> 18:20.560]  oh maybe yeah
[18:27.200 --> 18:30.400]  you know when you're having trouble paying that's why
[18:33.120 --> 18:39.520]  because it's okay okay I'll try to play a song
[18:45.040 --> 18:51.520]  where is it
[18:57.280 --> 18:59.520]  there's a second part
[19:12.000 --> 19:15.120]  Kathy can you hand me your keys okay
[19:20.960 --> 19:25.200]  so that was to show that programming is fun but programming the real world and touching
[19:25.200 --> 19:32.560]  actual things is a very engaging way to get kids and people that are not hardcore geeks
[19:32.560 --> 19:41.360]  interested in what we do with these programming computers that was all go to the oh yeah go to
[19:41.360 --> 19:48.480]  the micro blocks website if you want to learn more about it remember micro blocks dot fun small
[19:48.480 --> 19:58.160]  fast human friendly that's our website we have very nice if I may say so learn page with a lot
[19:58.160 --> 20:04.320]  of tutorials micro box is also translated to a lot of language I forgot how many the code is also
[20:04.320 --> 20:11.440]  translated just like heavy and more translators just like heavy yeah and if you want to help out
[20:12.080 --> 20:19.680]  in our site there is a whole section about how to contribute and we have a space for everyone who
[20:19.680 --> 20:32.640]  wants to help out thank you do you have time for questions just maybe one or two right
[20:35.760 --> 20:36.640]  any questions
[20:42.000 --> 20:48.960]  is it expensive I was getting asked that a lot at the booth yesterday can I just
[20:51.280 --> 20:58.080]  because we were doing some demos in the sfc booth and the range if I can pull this
[20:58.880 --> 21:06.640]  how much was this maybe 25 dollars m5 stack probably even less than 10 for the m5 atom
[21:06.640 --> 21:12.080]  the micro bits were retail at 15 until the pandemic supply chain shortage is now there
[21:12.080 --> 21:20.000]  20 or more the m bits what was this one now 12 dollars 25 the pico edge is maybe 10 this is
[21:20.000 --> 21:26.720]  maybe 25 so I would say they range you know less than 50 dollars and then you can buy some of these
[21:26.720 --> 21:35.040]  educational boards just show you like some of the small boards with stuff already included
[21:35.840 --> 21:40.960]  with stuff already included so you don't have to learn but the new robot aston.com pico ed board
[21:40.960 --> 21:46.320]  this is like 50 dollars but it has all these sensors and actuators and then you can pull apart
[21:46.320 --> 21:52.960]  the bricks as they're called and and use cables to put them back together this I want to say
[21:52.960 --> 21:59.680]  boarding is free though yeah yeah all the ranges from zero to and the cheapest of the
[21:59.680 --> 22:05.680]  ESP 8266 there are a couple dollars but then you have to buy the sensors and actuators I actually
[22:05.680 --> 22:09.920]  find for teaching you probably want to buy something with integrated stuff and then you
[22:09.920 --> 22:15.280]  can buy all these kits and plug them together and run robots and the robotic kits there's a ton
[22:15.280 --> 22:29.600]  of hardware out there next question so first of all in the learn site uh you're going to
[22:29.680 --> 22:36.960]  find some resources that are like full class classes like let's say this one that teaches
[22:36.960 --> 22:43.360]  you about maya numerals we also try to do activities that are not just about technology
[22:43.920 --> 22:49.520]  right so we can get a more diverse audience interested if you make a project out beats and
[22:49.520 --> 22:53.600]  bites that's going to interest that's going to interest probably the people in this room
[22:53.600 --> 22:58.720]  but you're already interested with you're not the target audience right but if we talk about maya
[22:58.720 --> 23:05.120]  numerals maybe people who are interested in history or culture are going to see the value in
[23:06.320 --> 23:13.280]  programming and microcontrollers so that's a whole activity and then you have actually
[23:13.840 --> 23:20.400]  drag the the screenshots pictures into the IDE and they will load and then you have a teacher's
[23:20.400 --> 23:26.560]  guide with extra information about what's being talked about and then there's we've we've done
[23:26.640 --> 23:31.920]  these things called activity cards and i put together a kit with a with a manufacturer and
[23:31.920 --> 23:38.160]  they included these activity cards 10 two-sided cards in the kit and there's things like flashlight
[23:38.160 --> 23:46.480]  tag and you know sound and um two button texting it uses two micro bits and use tilt to find the
[23:46.480 --> 23:52.560]  letters and punctuation and button a and b to to find the letters and and add and you can actually
[23:52.560 --> 23:58.160]  text messages directly between two micro bits for example or clues or other boards
[24:02.800 --> 24:04.160]  what do you mean can you code
[24:07.600 --> 24:12.000]  we don't want people to have to go through this hurdle that's why we're making micro blocks
[24:12.000 --> 24:20.400]  so you don't have to care about uh beats and uh bite codes no this is coding yeah you can you can
[24:20.400 --> 24:26.720]  see the ipode off codes if you want and you can build other editors to the vm if you want a text
[24:26.720 --> 24:39.040]  based editor on top go ahead um i'm wondering i'm familiar a bit with the micro bits and um so but
[24:39.040 --> 24:45.440]  what you do is you add sensors and or you put them in little overcards i think like that could
[24:46.160 --> 24:54.400]  yes yes if you go to the learn side again uh there's you can select the micro bit here
[24:55.120 --> 24:58.640]  and you'll see all these activities for the micro bit and a lot of them are using external
[24:58.640 --> 25:06.640]  sensors like this one uses motors to make a a micro bit robot this one uses a ready made robot car
[25:07.360 --> 25:16.560]  uh a lot of them use external sensors and actuators so for example you ask i deliver
[25:23.520 --> 25:28.080]  there's just five commands that send of the radio forward back left right and stop every
[25:28.080 --> 25:35.360]  time the buttons go up i stop and this one's running out of battery so the other one's faster
[25:35.360 --> 25:46.480]  oh we're over time okay thank you everyone
