Raspberry Pi Pico W microcontroller review, plus tutorial connecting the board to a BME280 sensor module to create a wireless weather station that transmits temperature, pressure and humidity readings to a web browser.
On this web page you can find the wiring diagram and a link to the final code:
www.explainingcomputers.com/p...
The excellent Pi Pico W "getting started" instructions from the Raspberry Pi Foundation are here:
projects.raspberrypi.org/en/p...
The page with links to download the MicroPython UF2 file is here:
www.raspberrypi.com/documenta...
The Pimoroni BME280 sensor I used in the video is available directly from Pimoroni, or on Amazon.co.uk here: amzn.to/3Q18Rjy A compatible board is available on Amazon.com here: amzn.to/3PXnF1q Note that these are affiliate links, and that as an Amazon Associate I earn a commission from any qualifying purchases you may make.

IN CASE OF DIFFICULTIES:
If during your experimentation you end up with a Pi Pico W that executes a program that you cannot interrupt by pressing Ctrl-C or Ctrl-F2 in Thonny, you can return the board to its factory state by holding down the boot select switch, connecting to a PC, and copying over a special UF2 file to reset the flash. You can find a link to this UF2 file at the bottom of this page:
www.raspberrypi.com/documenta...
Note that after execution you will have to reinstall MicroPython and any required libraries, such as the one for the BME280. All programs will also be erased! Hence, during program development, it is wise to save a copy to both the Pico W and to the PC you are working on.

Great parenting idea! I'm going to put that one in my back pocket for when my son comes of age. The sheer variety of microcontrollers and SBCs will be overwhelming in a decade. I suppose it'll make for some fun toy robots though.

I have watched MANY tech videos. You are EXTREMELY good at making these kinds of videos. They are to the point, clear, cover the important parts without going down rabbit holes - and best of all, provide quality resources that actually help. Please keep it up! And if you arent already covering this topic and are very brave, consider ROS2 tutorials (without using containers). Thanks again. Subbed. (I’ve seen your work before but have no clue why I wasn’t subbed already. I just assumed I was already as you’re that good!)

Once again you show this is a 'real' computing channel as opposed to a gaming channel so many of the bigger ones are. It’s surprising how many people want to learn about the things you show us how to do. I also think you have one of the best comment sections full of knowledgeable people.

As usual. One of the best videos. I must say " Nobody can explain things like you"... Thank you for such an amazing tutorial.

@graxxor 3 месяца назад

Your channel reminds me of those old BBC coding programmes that they used to show when I was a kid... Filling our heads with fancy ideas, sparking our imaginations and above all showing us that this arcane magic was within our very grasps if we just pushed our envelopes a bit and tried something new. I honestly feel that the Pico W is now where the original RPi intended to be... with the added benefit of wifi!

@John.0z Год назад

It's funny, but I originally bought my PiZeroW to do that task... and have been too "distracted" to get it running. Now it is not just possible, but easier, with even less hardware, and even lower power demands. The way of the computer world in microcosm. Thank you Chris.

@PoeLemic Год назад

Yeah, every generation gets faster and cheaper. Probably even easier. I just love how Computers are so great for our lives.

@kaiying74 Год назад

It's funny but I have a PiZeroW I purchased for this too but haven't used because I couldn't figure out how to power it outside. Thanks Chris for making me aware of the PicoW, I'll be grabbing one of them now.

@John.0z Год назад

@@kaiying74 Jamie, I found that one of my USB power banks for adding power to a phone will run a PiZeroW. The other one will not. But it is worth your trying a few before buying if you too have the need to power one outside and without any trailing wires. Obviously the same power bank would be great for a Pico.

@Cherizer Год назад

Although relatively simple, this video reminded me why I love tech myself! The moment you launched the website, I knew it will work, but it still felt satisfying seeing it in action. Well explained and I really hope it will help newcomers with the microcontroller basics.

@LMacNeill Год назад

What a neat idea! I live in a rural area, so all the weather apps that I can get on my phone and the internet do not show me the weather conditions in my immediate vicinity -- they all grab data from the nearest official weather station which is easily 20 miles away, perhaps 25. This would give me a great way to quickly check the conditions outside my house -- even remotely, if I opened a port on my router and redirected the Pico's web-server to that port. Plus it'd just be a cool flex to be able to show this off to my friends and family. 🙂 Thanks!

@ahmad-murery Год назад

In this hot weather I think it's a good idea to use PICO to control a fan and a humidifier to justify the room temperature, or maybe we can clone an Air Conditioner IR signals then use that to write a little program to make it act like crazy, or, what about converting an old washing machine with mechanical program selector to a digital one. So many applications for this lovely little PICO Thanks Chris and have a nice weekend

@robginsburg6413 Год назад

As ever, a really interesting and engaging project, superbly explained. Thank you, Chris! Perhaps well understood by most, the two major learning points for me were: a) the importance of indenting code; although I could get the code to read the sensor and send the reading to the shell in the first segment of the tutorial, an error was generated in line 53 whenever I later tried to run the full code. I eventually worked out that the 'while True:' statement, and subsequent lines were not indented appropriately on my Pico code. b) the second point was to remember to press the 'STOP' icon before trying to run newly edited code. Very satisfying to get it all working!

@Jimmy_Jones Год назад

What's wrong with the existing MQTT libraries?

@SergiuszRoszczyk Год назад

@@Jimmy_Jones have you seen C one? There is one from Paho but it is for C++ and not exactly works on Pico. It works fine on STM32 HAL.

@CallousCoder Год назад

It shouldn’t take too long as it’s also available on other wifi microcontrollers. But I agree that it’s a priority requirement for networked microcontrollers.

@SergiuszRoszczyk Год назад

@@CallousCoder there are some use cases. But I want C so for now it is screwed anyway ;)

@CallousCoder Год назад

@@SergiuszRoszczyk I agree, but I think it won’t take long for a C MQTT client to pop-up. It’s a simple enough protocol, but it depends on the ip stack implementation of the pico how easy it is to use. Especially TLS, that’s always non-trivial. But when MQTT C lib is there, I’ll finally be in on the pico. The pico W finally made it a viable platform for me. And I’m actually excited for it now. On its release I didn’t see it as a rival to the ESP32s I tend to use.

@parrotraiser6541 Год назад

Great, as usual. Especially in projects that aren't likely to have external documentation, legibility > golfed code every time. (When the time comes to change something, you'll know why.) I would quibble about the output format, though. Transmit only the variable data, (identifiable as fields, CSV being a good first choice), not the constant decoration. KISS. Dollars to doughnuts, a subsequent change will make it necessary to process the data in a different way, (e.g. as input to some sort of controller), and you don't want to have to dig the numbers out of the surrounding text. That can always be added in the HTML.

Yes, I too am always impressed by wireless real-time connections and measurements from my own devices and programs. Something magical about it. Like when writing my own code directly to the PC VGA and Serial controller registers. No BIOS, no DOS/WIN, no Driver Libraries. This is not quite a fully satisfying bare-metal driver but it does feel nicer than the vast majority of IoT "commercial" development systems and interfaces. (Always too much bloat for local and personal use. And nearly always WWW internet dependent too.)
