Your challenge, Chris, is quite clear; creating a Pico controlled tea-making network.
:)
It might be better to wait for the upgraded model, the Raspberry Tea-co.

I see a Wallace and Gromit rabbit hole here haha
Eventually he fully automates his youtube channel production with picos and other controllers. Automated recording, editing and uploading, machine learning based video ideas from analytics. Only, he is still the host, and the machines are now his boss. But at least there is infinite tea.
This is me officially letting you know I’d like to see more videos on raspberry pi picos and microcontrollers. Thanks, from The States
My first thought when you started that board was "Oh look, a Cylon." Then having your By Your Command title straight afterwards really tickled my funny bone. Small things amuse small minds I guess. Good episode, as always.
I’ve never used a micro controller but I appreciate their simplicity in doing a single job well. No lengthy boot times, updates or antivirus to worry about. I’m thinking of all sorts of home automation ideas.
@Hilldweller ... Or maybe not? When I think "simplicity", I very explicitly don't think "add it to the internet". Instead I think stuff like "use headphone connectors to network them!"
Another important difference is that [most] micro controllers support analogue sensors whereas something like the Raspberry Pi only supports digital sensors.
Yes. Think of something that is better off done automatically and make it happen. Like a keyboard macro for your house.
@@hxhdfjifzirstc894 that would not be automatic, then
@Hilldweller ESP8266 is dirt cheap and perfectly adequate for many purposes. Very easy to integrate into bigger projects too.
I dont comment often, but just wanted to say - love the channel, you make fantastic videos!
Awesome! Thank you!
Yes, I think another video on various use cases of the Pico would be cool. Maybe invite viewers to submit their working set ups to show and tell? Or anyway just to get a flavor of the different ways it can be used.
I was thinking how might the Pico send sensor data back "home". Let's say when controlling a Robot wirelessly over a distance > bluetooth range? I'm sure there are lots of ways but 802.11s Mesh Wifi could be a peer-to-peer solution? A video showing its use with OpenWrt here: th-cam.com/video/cw8ykKgVKbM/w-d-xo.html
Instead of paying $50 for a USB rubber ducky, you could use this $4 Micro Controller(the pico) instead, although it would lack the USB storage mirage, it's still really useful for just $4.
Look up the "Duckberry Pi", so much cheaper but it's the same results.
it´is so satisfying when one test a new hardware and see the LEDs turning on for the first time.
The Microcontroller version of, "Hello World" 😉
It's literally the first thing I did, too. Reminds me of when I first started learning Assembler. It was back in the day when DOS programs always had a copyright string on startup. There was a very specific sense of accomplishment seeing it print *my* copyright string for the very first time. And that sense of "w00t!" still arrives with every initial "hello world," whether it be text, blinking lights, or whatever, decades later.
@@NorthernKitty You can make yourself a little piece of code to morse "Hello World" 😁
Got my Pico PIO counting at 62.5 Mhz and not missing a count. It will output square wave at 125Mhz with less than 200 picosec jitter! Hope to use it in the lab to do fpga style functions at fraction of cost. Much potential in robots and science hardware. Thanks for a great video!

Another great video. Really appreciate your efforts, and the continued excellence of your work. Look forward to your program each Sunday morning.
Thanks! 🤗

Mr. Paul we are ur fans too❤️👍
You both are great guys. I am your and his fan
Wow Paul never knew you commented : )
I'm starting to think I was lucky there weren't these kinds of toys when I was a kid. If there had been, I would have never left my room... except maybe for a monthly visit to an electronics store.
Except you wouldn't leave your room to go to an electronics store as you'd just order everything online instead
I'd have made a smart suit out of all of these tiny boards lol
This! This was what I did (15 years ago) for nearly an year after college. I stopped because I had to find a job to put food on the table 😂😂😂
In the 80s and early 90s I had an electronic components store on my way home from primary school. It was mandatory visit every single day and guys there were very helpful with dropping hints on resistor, LEDs, small DC motors. They influenced my life very much and in a good way.
@@SergiuszRoszczyk
You lucky bastard! I needed to take a 30 minute bus drive and walk for another 15 minutes to get to the electronic component store. And the staff there wasn't interested at all to help a young kid in his projects.
Later I found a TV repair shop around 15 minute bike ride from home. Component selection wasn't that great, but the owner was always ready to help and almost always found a substitute component when I showed him the schematics.
I am impressed. You've done it again. My experience with Micro Python has just doubled. Thank you for taking the time to educate us.

I am an experienced amateur programmer, having programmed PICs, Arduinos, BBC Micro:bits etc for years. I have bought two Picos along with 3rd party experimenting boards and struggled for a while adjusting my thinking to programming the Pico. I have read some very wordy documents from these suppliers, possibly too quickly, and missed one or two crucial bits of information before starting my experimenting. Having watched your very clear video this morning I immediately discovered where I was going wrong and all is now well. You have done it yet again Chris, do keep producing your excellent videos! There are lots of us out here that will watch everything you produce because we will always learn something new and very useful from them. More tutorials on using the Pico itself would be most welcome. Many thanks to you!
Thanks for this -- great to hear you have things working. I have a follow-up Pico I/O video here: th-cam.com/video/TDj2kcSA-68/w-d-xo.html -- and another Pico planned, currently for May 1st, although that may change.
yes please .. take a look at micro:bit and the likes .. love your content, your voice, your editing .. sooo much effort
ESP32 etc...
Great video for people like me who bought a Pico entirely on the basis of it being $4 and being familiar with Raspberry Pi as a computer but with no programming experience. I now have a $4 flashing LED, the world is my oyster!
I could listen to you explain stuff all day Chris. 👍 The soldering part... "40 Shiney, molten, metal connections later..." 😂 That kind of silly dry humour cracks me right up. I love it.
Also, thanks for all the time you put in helping us plebs. 👍👍
Thanks 👍
Oh yeah, been waiting for raspberry pico from my favorite TH-camr
I've learned more about this in a few minutes on your video than in hours of struggling with it other places on the net. Well done.
I like your channel with dry English humor and great tutorials. You are a great teacher so keep it up!
That british wit of yours, Chris. This microcontroller has everything; this is the first one I see with an onboard temperature sensor.
I'm sure you got a lot of exciting ideas. I'm looking forward to see what you got in mind for it.
Now I have my own Pi 400. Guess who is responsible for tempting me to buy one.
And now I want this microcontroller to go with it.
That's the best intro to the Pi Pico I have seen.
Chris - thank you for another fun and informative video. I appreciate your dry humor. As I sit in now unfrozen Texas on Sunday mornings, I tell my wife it is time to listen to my favorite Brit. Personally, I would appreciate more microcontroller videos, especially looking at communications between the microcontroller and a single board computer using, say, SPI. However, I will comment that, with the advent of the Pico, there is more overlap with another of my favorite channels - Dronebot Workshop. In an ideal world, the two of you could collaborate on some videos, but who knows? Again, thank you for another enjoyable Sunday morn!
I've never seen any explanation like that ever, I even paused the video to say THANK YOU!
Thanks for watching.
There are lots of Pico intros on youtube. Most are too fast and confusing. Your video is easy to follow, I'll use this one after I buy a pico.
Yes, I would like to see more microcontroller videos, maybe a comparison of an arduino uno to the pi pico
Another popular microcontroller is the ESP32-PICO-KIT, or any number of variants of the ESP32. It would be nice to see a comparison between the RP PICCO and the ESP32 PICCO. Great content as always and thanks for sharing.
Fantastic episode, Chris - an incredibly clear explanation of the difference between the Pico and 'full fat' Pi. Please please do some more videos exploring the possibilities. The speed it started your running your code when you switched on the powerbank was just jaw-dropping!
Thanks Alan. There seems strong support here for more Pi Pico episodes! And I agree that the speed of running the code is really cool.
I appreciate both this video and the Glen A. Larson reference.
That was a very simple and elegant demonstration of the Pico's capabilities and got me thinking about the possibilities. Thanks very much as always! I can't believe it starts immediately after power on!
There's some fantastic macro filming in this episode. Really clean soldering job and all in focus. And yes, would love to see more microcontroller videos!
You made me buy my first Raspberry Pi, and now i'm ordering my first Pico because of this video. Thank you.
Enjoy your Pico! :)
the cup of tea joke hit me so hard because of the dead air between the joke and the transition. so good.
Chris, I always enjoy your content as it is so well produced and “explained”. You might need to start another channel called Explaining Microcontrollers. :-)
When the Pico was released , I didn't buy it as I thought I didn't need it as I have many other micro-controllers , But as soon as i saw your video and satisfying electronic imagery ,I feel I should buy one....
I know, I held off buying the PyBoard (-or rather a clone-) because I though "that would be like buying the kitchen sink" [proverbial] and "seeing as I have everyting BUT the kitchen sink already, I'll probably get by". But then it was Three-pound Sixty, plus an order from either CPC or Pi/Hut¦Moroni (which was going to happen anyway). Now, seeing as I have two "Black Pills" (the lesser and the great) it was not a stretch to end up with two Picos already (from qualitatively different sources). If a system is good and keenly priced AND vulnerable to ham-fistedness in its usual use, it's probably worth having a back-up.
The best explanation and demo I've come across since purchasing my Picos. Thanks for making this such a breeze and easy to follow!
I somehow missed the releasing the Pico, I'm really amazed by it and it has honestly rekindled my love for micro-controllers!
Great. :)
A Pentium running at 133 mhz was the pride and joy of our family once. Obviously we also had a 3dfx Voodoo card with 4 mb. YES! Really! That was the stuff dreams were made of and made our house where we all played, much to the despair of my mum who provided us with crisps and lemonade.
This pico (or any other microcontroller) can easily and by far (orders of magnitude) outperform any modern computer at tasks it is designed to do. And there are many of them computers just can't do
I’m looking forward to a day when I have time to tinker with things such as this again. Teaching remotely has kept me away from being able to explore how I could use something like this. I know I’d enjoy seeing what you’d do with it, if you’re so inclined. Cheers!
The single best introduction and explanation of the Pico on the entire internet. Definitely would like to see follow-ups with some practical applications. Including how to use that onboard temperature sensor.
Just got a raspberry pi and found this channel and have been binge watching videos since 2016 apparently. Really great channel that deserves more subs!
Thanks for watching!
Chris, yet another entertaining, informative video with the added easter egg of including Glen A Larson's ground breaking work of using flashing LED's in Battlestar Galactica and Knightrider. As always you have made my day and by extension the world a brighter place. Many thanks. P.S. It would be great to see the Pico being used to control a motor.
Hi chris , i'm Christian. (CD)
I can't help waiting for next pico video !!
Thank you Mr. Barnatt for making this video about the pico. It was very educational. Raven
I don't think there has ever been a retail product that has been so affordable and yet you can do so many different things with it. In addition to microcontroller functionality, you can also use it as a directly programmable computer by installing Picomite and writing/running BASIC programs on the Pico itself via terminal software. At the default 133 MHz speed I'd estimate it's 50 times faster at interpreted BASIC than a Commodore 64. Not to mention it'll happily run at 250 MHz. The low power consumption when underclocked makes it ideal for managing my solar-powered motion sensor light system where I want to maximize battery life as much as possible. It's a great little device.
Very well said! :)
Pico is one of the best codenames for the PI.
@Jack Warner why?

Great video Chris! I am wanting to teach a younger family member some electronics / programming and the format of this video will be nice start to get the ball rolling. Would be very excited to see some 2 wheel robot motor control examples and some examples of using sensors. Much love from Sheffield, 8-bit.
This small affordable device points the way to distributed processing. Like imagine a robot 🤖🦾 hand or leg 🦿basically controlling itself partially. Like I heard legs of an octopus 🐙 control themselves. So YES... please continue! Thank you! Have some tea! 🍵
Excellent video. Extremely clear and to the point. For a guy that grow-up with Spectrums, 2068s, C64, C128s this channel makes me feel like I'm on my game.
Thanks for this -- and I imagine you will like the video posting in a few hours! :)
Your mind reading skills have reached god mode 😊
I bought a couple of pico:s the same day as the release. A Pico Explorer Base is the next thing I'm going to "invest in". It has been sold out for a long time at Pimoroni but seems to be in stock again. 😀 Didn't know about Thonny. Great tip and excellent video as always. Thank you.
Awesome ! I got one of these in a Kit with accessories in a bundle when I bought my pi400. When it arrived I had no ruddy idea what it was, now I do, thanks Chris !
Ah, Sunday with Chris! Please keep doing this for the next, oh, 30 years. Thanks -
:)
I watch the contents very well, I wish you continued success.
Thanks.
Hi, useful to see. Be interested in seeing it compared with Arduino and/or Teensy etc to see why one would choose them over it or vica versa.
Regular Arduino's (AVR) the M0 gives you more but the gotcha is it is most likely NOT tolerant above 3.3v which AVR's are 3.3 and 5v tolerant. Teensy being a bigger arm will absolutely smoke this board as would anything sporting a STM32 F4 ( Cortex M4 ) the G series is massive in robotics as not only is it a grunty CPU but has FPU among a huge range of I/O including FDCAN which is essential for robotics / precision.
If you are just starting out you can’t beat that $4 price tag.
@@zac_in_ak Sure price is one factor I suppose but there really should be more involved than that, pound for pound an esp32 is a better overall choice than this board and its err cheap for alot better performance and options.
@@sethrd999 I grabbed it because of its decent performance and cheap price since I'm new to microcontrollers and don't even know what I need or want. A good way to dip your toe in. trying out circuitpython and micropython
Oh yes, please do. And not just microcontrollers but also components, specifically those useful for smarthome designs: sensors, relays, converters etc. Thank you!
More videos on pico and micro controllers please. Any content from you is always good content.
On the brighter side, I used to run 'Doom', 'Dark Forces', X-Wing/Tie Fighter' and 'Rise of the Triad' on my 133MHz Pentium. (Hehehe)
I know, we are spoilt with CPU power these days.
And paying 100 dollars for 4 megabytes of ram. Man, I don't miss those days. 😂😂😂

great video , yes i would love to see other micro controllers being featured , eg esp32 etc , even using a pi to read data from them
Great video. More Pico videos please. We definitely need an EC explanation on Programmable I/O
Just received my pico''s yesterday and exciting times are ahead! Looking forward to what you come up with using the pico! Well done!
So that's what a Pico is all about! Thanks Sir Chris.
That was.. illuminating. I'd had no idea how those things worked. Now I have my first clue! :D
As always, a very well done video. The practical demonstrations provided are always much appreciated. I would love to see more videos on the Pico and other microcontrollers.
Yes Chris, after that introduction to a Pico controller I am keen to see where you want to go with it.
Another top video for a Sunday's evening viewing.
Thanks.
Yes more detail. I need some help with getting started training myself and my homeschooled daughter
A good, simple add on to his program would be to add code to take one of the GPIO inputs, and add a trigger to start, then maybe count the number of trigger presses and make that many iteration loops ... aka the old SIMON game.
Check out adafriut and sparkfun lots of info
Now I want to make my own gamepad controller and use the Pi Pico as the brains.
Well - what are you waiting for? Just go for, buddy!
Hey I recommend a PvP arcade gaming station! Add a coin function too for some cash lol
the Pico supports HID emulation out of the box, so that is considerably easier to set up then it is with ESP32 and other atmel micro controllers (though there are some limitations with the Pico as far as analog inputs IIRC)
@Jim McIntosh a shop near my house had it, the owner built it I think, it didn't have a coin slot but had a switch he will press whenever someone wanted to play. He passed away now, Lots of kids including me came to play there.
Actually if you have a raspberry Pi I don't think you will even need this. Just connect the button and joystick wires to the gpio pins directly and program it to recieve input.
Chris your well presented videos have opened up a whole new world of exciting computer project ideas, I for one would be grateful should you decide to include further micro controller projects like this one. Many thanks for your inspiration.
Thank you very much. So clearly explained. The little real world experiment had been the cherry on the cake.
My day is complete :)
Night night. 😴
😂 awesome reference to Knight Rider and Battlestar Galactica! 👍
Great shows.
free fire free fire Pico
Excellent explanation, sir. Having never worked with microcontrollers, this video sparked some interest for me as it doesn't seem as complicated as I thought it was for all of these years.
The Raspberry Pi Foundation have, as usual, done a lot of work to make getting into it as easy as possible.
@@ExplainingComputers Indeed. Hats off to them.
Great video! Now I understand the basics of what a micro controller is vs a computer. Thank you!
I was waiting for this from the launch if it!!!
I got there in the end!
The Pico became self-aware about 30 seconds after the video was recorded and ever since... Mr. Screwdriver has been missing.
:O
Its ok , Chris has dispatched a search party comprising of Stanley the Knife and Mr Scissors..
Please, sir, I want more. Your explanations of this brave new world of SBCs and micro-controllers are quite facinating.
Great set of videos, have been binge watching them in the last days, THANK YOU so much for taking the time to make such good content.
Thanks for watching!
Yes, More!
Nice video bro 👍👍
I would love a small tutorial series on the pico!
Excellent timing -- my Pico arrived a day ago. Coming from Arduino/ESP32 and C, your intro was spot on informative. I would look forward to another Pico project.
It would be great to see more Pico. As always enjoyed the video.
Fourth?
In any case I’m very glad to see you take a look at the Pico! By popular demand I assume?
I count you as third -- so a bronze medal! :) And you are right the Pi Pico is reviewed here by popular demand. :)
@Hilldweller Exactly what I thought when writing that comment. Sadly my experience of forth is limited to my brief interest in minecraft circa ten years ago.
003mer makes videos using the pico and fourth. Check it out. He's top notch also.
I think more Pico content would be fantastic! I got my pico a couple of months ago, and haven't yet been struck by inspiration as to what I should do with it.
very interesting, I have long left my hobby in microcontrollers because I have complicated ports and programming, after seeing your video, the technology has changed a lot, it seems simpler, I want to start again

Thanks, Chris, very good presentation. I hope you will not stop here and go deeper explaining multicore, interruptions/irq, exceptions. memory control, stacks, registers and all other good stuff which is usually taken care by OS and now we have to do it by our self.
Much appreciated. You explained the basics of getting the Pico up and running very simply and clearly. Yes - please do go ahead with a further video on additional I/O tasks.
Thanks for this -- the additional video is here: th-cam.com/video/TDj2kcSA-68/w-d-xo.html :)

I really appreciate your channel! Even seasoned geeks can learn a lot from you!
Thanks Chris.
I particularly enjoyed the "cup of tea" comment!
I could do with a good reason to learn python, so please do take us into the world of microcontrollers.
Anything which can get processing jobs done quicker and cheaper is worth looking at, and this tiny controller looks like a great introduction to the genre

This is where I draw the line. The Pi team has gone too far.
Yeah, I had to close my tab and go cool off for a few hours before finally finishing the video. smh
this guy is as fun as explaining raspberry pi to me back in 2014
I love your videos. I would like to see more Pico videos, perhaps using them in conjunction with the regular pi's. Looking forward to more of your videos.
Thanks Chris, I'd very much appreciate to see more controller videos from you Chris.
