A very thorough presentation. Not rushed as many fall into the trap that they know their subject, so it's delivered at warp speed. One of the best I have viewed.
The considerable effort which has gone into producing this has resulted in a video which is first class, a treat to watch and seamless in its presentation! You communicate carefully, logically and clearly, leaving no room for misunderstanding. Thank-you very much indeed!
The best introduction to the Pico I have had the pleasure of experiencing. As usual, a great presentation from a terrific communicator., Bill (Thank you).
@49:03 plumbing excitement! must be near time for a snack. All very clear and so a Godsend for those starting out and a very useful illustration/reference for the rest of us.
Best video I've seen on TH-cam so far this year. Come to think of it, best this decade! Thanks for a fascinating, gentle, logical, easy to understand beginner's guide to GPIO.
I watch your videos all the time. They are very professional. I usually give you a like and watch it to the end, when I have leisure time. thanks for sharing your knowledge.
Plus skip past the part where he reads all the specifications from the spec sheet -- the same as all the other intro videos do to waste time and make their videos longer without adding any value. Not as bad as all the videos merely taking something out of a cardboard box, but still annoying. Then he has to perpetuate the myth that the Pico is a $4 board (like the myth of the old C.H.I.P. being a $9 board). Shipping can double, triple, or more the actual price you pay, but few videos are honest enough to mention that. It would be better to just skip all the fluff, increase speed to 1.25x, and get right to the I/O part at 23:36.
34 minutes in, you talk about not wanting to be interrupted by your own interrupt, in the "int_handler()" function. This was a quite serious issue in my software career! OS/2 could "trap" and would print a trap message, which always began with "TRAP". If it got a trap while it was handling a trap, we called it a "TRA" because that's all it would manage to print out, just the first three characters. Those were rather unfortunate, because we really wanted to see what went wrong! Not many people got to touch kernel code, after enough incidents... Thank you so much for these tutorials, by the way; I'm learning a lot from you.

@@transsi quote "Sometimes it even worked" - > Really? Not on any PC of mine that time ;) As I remember there were only a few IRQ and DMA channels free and the next troublemaker was IRQ sharing (totally funny with PRO audio getting spikes every 10 minutes or so).
You came late in the race for Pi Pico demonstration but you certainly have made an awesome tutorial. It covers almost everything which is circulating around so far! Keep it up!
Congratulations on an excellent teaching video for those wishing to learn through the Pico. As good as "Explaining Computers" which is a high compliment.
This instructor will hold your hand and walk you through the jungle and you'll think it's the park! I learned new things. What I didn't learn new, I understand better. Thanks!
Grrrr... step one may just be finding a micro-usb cable that actually transmits data. I had half a dozen cables lying around, and was beginning to believe I bough a bad Pico. I ordered a cable that specified data, and magically, everything works. Once past that hurdle, really wonderful tutorial. Logical, concise and well-presented and edited.
Been struggling with a pico for a week, I just learned more in the last hour than I did all week, enough to write my own code to get the projects done I got the picos for.
Super interesting demos. In fact, the terminal and the way to program the Pi Pico takes me back to the 80s when I was programming my Commodore 64 but the similarity ends there. The quality of your preparation and the demonstrations only make the Pi Pico more attractive and enjoyable to program. Thank you.
To check zero of ADC you may connect directly the pin to ground or analog ground. If you get reading 0 this mean that the potentiometer is not perfect. If the reading is different from 0 this mean that ADC of controller have a problem in design. ( I've seen other video on TH-cam where user have same problem with ADC) The video is very informative. I have to stop few times to be able to absorb all information given :)
Thank you so much for, unlike most TH-cam creators, speaking at a slow pace. I appreciate that a lot in instructional videos, it helps tremendously. Great video, visually and content wise.
Love how you describe the items you working with. How you give super explanation of the microcontroller, just got my 2 picos I know years late but I’m learning lol
I just spent hours looking at various videos on programming the pi Pico using micro python. This was by far the best as well as easy to follow presentation. Thank you!
At 42:00 you discuss the ADC conversion which is providing 12bits and your inability to reach zero, others have observed this as well. I have not dug into the details of the read_u16 function, but it's logical to assume that the bits are being given to you as 12 bits in the top of the u16 location which would explain why you see a value of 64K-1 at the top end and would have fuzz in the final 4 bits. I would suggest you might see if doing a bit shift right 4 times gets you much closer to zero at the bottom and give you the expect raw value of 4k-1 at the top. Great world wind exploration of using MicroPython on the Pico, I am considering getting the Toolshain in place to try out access via C++, given this would let me play with the second Core (which I assume it dormant using MircoPython).
Really enjoyed this video of you taking the Raspberry Pi Pico to the breadboard gym you put together to put it through its paces. So much power in such a tiny package. Will make IoT device development much more exciting.
Very useful intro to using the Pico. One minor niggle is could you please put comments into your code. It's great when reading just after watching but coming back a few days later to review code some of the details of why you do things means a return to the video.
Very nice getting started with the Pico video. I like the way you make no assumptions of prior knowledge and cover necessary bits. But, mercifully keeping it brief so as to not turn off somewhat more experienced viewers. Admittedly, that a fine line. For example, my mouse was posed to skip the solder flux cleaning tutorial 😀. But it is probably appropriate for most Pico beginners.
To the non- zero ADC Problem at 41:50, my guess is, that the problem is actually that we cast a 12 bit value into a u16 cast variable. Since we get 65535 at full potentiometer state, the ADC value seems to be MSB aligned in the u16 variable "potentiometer". This leaves the lowest 4 bits in a undefined state and might be the cause for the random non-zero values in the serial monitor. I personally have no experience (yet) with the pico and micropython, but again, this would be my first guess. Otherwise i really liked this video, it will be a great help for me getting started with my picos :) thank you!
my second thought on this is, that the ADC really returns a 16 bit value, but with only 12 accurate bits. In both cases, i would try masking out the lowest four bits of the ADC result, and verify, if we still get a linear response from the potentiometer range.
I have watched a bunch of Pico Videos now .Yours is the best by Far. Btw I have been watching you since the start of Covid. Always entertaining and informative. Thanks.
I'm also thanking you for the information and enjoyable video that you have presented. I so much understand what you are describing because I went to school and study for it and I know that I should understand it so well but when you start to explain all the inner workings and the fundamentals, All the lights went off and the understanding screams came out loud. I thank you for your very good explanations and extreme and good showmanship. Your videos are good for training and leadership. The next generation and leadership needs this. thank you.
What a great instructional video on the Pico. I’ve been dragging my feet on getting one. Now I’ve got one ordered along with some accessories. Count me as subscribed.
Thanks for yet another thorough and informative video. I'm especially happy to see you explaining interrupts, and actually stating it's an important topic in the microcontroller world. A lot of video introductions to microcontrollers miss that.
Thank you for the time and effort you put into your videos. They are very professional and informative. I wish more instructive videos were produced like yours.
Sir, Thanks for introducing new microcontroller. my washing machine is not working due to control board failure. I purchased raspberry pi Pico board and programed for the washing machine. tested program in thonny IDE . Electromagnetic interference (EMI) or RFI is making GPIO 15 goes to high intermittently, even if program is not executed Please advise me to over come this problem
Hi, sir, your video on all tech is the most comprehensive I can found around. Thank you for sharing your knowledge to the rest of the world. Cheers. :)
I had the very same problem with 0V input to the ADC. It reads around 400. Scaling to 16 bits means shifting the 12-bit result 4 places to the left so you might expect 0V to bounce around 0, 16, 32, etc. The 400 count level seems to indicate a problem with the ADC. Any thoughts out there?
I am getting the same results and I contribute it to noise. The buck/boost converter is supplying 3.3 volts for the ADC Vref and also to power the internal ADC. That same 3.3 volts is also applied to the pot that feeds the ADC. I have measured 75 mv P-P noise on the 3.3v bus at around 1 MHz. 1/3.3 * 65536 = 198859 and 1/3.375 * 65535 = 19417 the difference is 442 which what you get. It is not the RP2040s fault but the power supply. Hope Adafruit or Sparkfun rectifies that in their board design with the RP2040.
What is the role of a controller? Why can't the raspberry pi directly control a motor, for example? Also, do I need both a driver and the pico to control a motor? Thanks for the great tutorials
Dear sir, (1) Va red colored knob power supply is how many volt?(2) Its supplying to what components? Tq for sure the best Intro to Pico. It also show, Pico is not just the hardware but also the codes (Micro Python) versatility compared to Arduino. Thanks again..
from all the specs, it is much more capable in every way. faster processor, higher ram/storage, and more connection protocols like 2 i2c's. also, it acts like a usb device so in that sense it is like the arduino leonardo as well. if you just need to control a couple of relays, or control a motor (like in this example), there's no real difference in using the pico or the arduino; they both will work fine for that. however, if you have a bigger project with multiple user inputs, sensors and multiple outputs including oleds with some graphics, and/or you need to compute the data from the inputs, the pico would easily have the advantage.
Good Video about the Pico. Just a short explanation from the Chemical site, about Isopropyl Alcohol also called Isopropanol or 2-Propanol. Your Mask which you showed is made to catch particles like bacterias Viruses and Pollen, but you won't stop any Isopropanol which went in the gas phase to entering you Lungs. I don't say Isopropanol in this Amounts will be harmfull to you, but I just say you also can let the mask away as it doesent do much on the intended usecase. The same mostlywill apply to the flux remover. I don't know exactly what it consists, but I expect that it will consist on a mixture of solvents. Which also will penetrate the mask while in gas phase. A better practise from the Health site would be to conduct this work an a well ventilated Area, or direct the fumes with a small fan out of the window.
36:43: It seems like oddly buggy behaviour that you're not sleeping after lighting the blue part of the LED. It's even apparent in the video, where it basically goes from green to off.
This is a great introduction to the Raspberry Pi Pico. Now I just need to get my hands one. Your introduction is one of the best ones that I have seen. Thank you.
Hello. I have a question that in the external interrupt if set led_green.toggle() utime is a large number say 20 and interrupt at the time led_green (1), when the interrupt time is over, there is still time led_green (1) but led_green doesn't turn on until cycle is over (1). Can you edit the code to make it work properly?
As for the potentiometers, there are ones that when you turn all the way down they click and turn off. Not sure what they're called but they have 5 pins on em.
He taught me more in one hour than my teacher taught me in a semester.
This video represents the extreme quality difference of new product reviews and demos.

4:28 Last time I checked, when power is applied to an LED, I emits light. I could be wrong though...
ESP32 can also use Micropython. Does Pi Pico have advantage over ESP32?
As for the potentiometers, there are ones that when you turn all the way down they click and turn off. Not sure what they're called but they have 5 pins on em.
