For the other Pico W / Pico WH owners out there: to get the blinking LED to work you need to swap out 25 on line 4 for 'LED'. So from: led = Pin(25, Pin.OUT) to: led = Pin('LED', Pin.OUT)
This is by far the best introductory video for the Pico I've seen on TH-cam. Very easy to follow, and everything worked fine. Thank you very much for getting me off the ground with it. Would love to see more in a similar vein. Pressing the subscribe button now!
Both your REPL guide and this one have been extremely easy to follow and a bit of a life saver. I was getting in a bit of a muddle from the setup pdf from the pi foundation on how to set up the pi, setting up cmake and all sorts of other things for vscode etc etc. Why they didn't just have a simple "Use Thonny in this simple way" is a bit beyond me but there you go
Thanks buddy! I´ve just received my first pair of RP Picos, and have´nt had much luck communicating with the board, till I watched this video. We´re blinkin´!!! ;)
this is the best explanation of Pico and thonny, all other videos just assume that you know how to use thonny although they title their videos : for Absolute Beginners !!! (which is my case. :) ) ... thanks a lot !!! . hope you can show us a step by step video of building and programming a simple pico robot

Hi Sir. Can you explain how we can install micropython machine module in python??so i can create some application in tkinter to control the gpio pins of raspberry pi pico.
hello, enjoying your videos but struggling to get anything to work on my pico. my project isnt compicated. just need a couple of outputs triggers when given an input. basic switches etc. cant seem to get any coding to work.
Hi, great video! May I ask you a question? I have a pico W but I can't get REPL to work! Thonny keeps telling me that the device is busy, i tried soft rebooting, pressing ctrl+d, ctrl+c, tried connecting pin 30 or RUN to ground for a soft reboot, but nothing, even tried deleting code.py from the pi. I am running Circuit Python 8.1, i don't know if it is my pi the problem, please do you have any suggestion?
Hi, I'm more of a C/C++ type of person. Is there anyway i can use the Plotter and the Shell in Thonny as an output for my C codes on the pico ?? I've written a code in C to output data for proximity sensor but minicom, putty and the arduino console can't detect uart output.
Man it's like the arduino IDE in simplicity.. but way better. Is there a way to get it easily working in VS code? I've seen two videos on it, but it seems like a giant pain.
Complete novice here. So let's say the pico is powered from a power supply instead of a computer. And then at 6:06 pico loses power which can easily happen. And then power comes back on. Should the code autostart or does it need to be connected to a computer again and with thonny stop/restart code and ctrl+D ?
If you save the name of your code onto the Pico as main.py then it will automatically run when power is connected, otherwise you will need to reconnect to Thonny and restart the code.
I'm on a mac. No go with your instructions. At this point the ESP32 seemed easier to get going. It's like there is a step missing I'm not seeing from the RPI documentation or your video to get going.
suppose if i close thonny then LED will stop working.in arduino if we close arduino IDE still project runs on board.likewise how it can be happen in pico?
I am a bit confused because i have done every step as described but the led doesn't do anything. The printed part is updating all the time when i run the program but the led not. What may be the problem?
Hey sorry for the late reply, if you are using a Pico W, they have changed how you reference the LED pin. It used to be pin 25 (but now that is used by the Wi-Fi chip), so you will need to change 25 with "LED", so that line will look like: led = Pin("LED", Pin.OUT) We have update our writte guide, and Ill Pin dnywh's comment who answers this so that other can find it more easily!
every thing is working fine , Program is getting executed by "Run" option, but there is no "download" option to burn the micropython program in the flash memory. When I am removing USB Plug from laptop blinking of LED stopped because it is not getting power through USB it is Ok, but when I am reconnecting USB with 3 second pressing of USB and port is also showing connected , then also LED is not blinking, unless I again "run" the program, that means program is not getting burnt in flash memory , How it can be done (this type of problem is not there with Arduino board)
Nice video, I am wondering, instead of using sleep, is there a way to flash the LED while a code is running on the PICO, like to run the flash led parallel to another program that's running. I don't know if it have to run in a different thread or how this would be approached.
One quick question how do I change the Port setting in Thonny, Thonny thinks my pico is at port 13 and my computer thinks the pico is at port 14. I have to edit the configuration.ini file, Port = setting but it keeps reverting back to Port = 13
I have had trouble in finding code you run on strip leds running pi pico any help please internal code led worked fine. I keep error example code 1 from raspberry pi pi pico libaray line no name pixel? Any help anyone.
This example of printing was just a demo, but print commands are incredibly helpful for debugging. If you have code that makes a series of decisions, you can put print statements in those decisions and see how it is "thinking". You might also want to double check that you are converting numbers correctly (maybe your sensor reads in Celsius and you need to convert to Fahrenheit), so your might print it out to double check that the Pico is calculating it correctly.

Downloaded Thonny and get a Site Certificate Expired error. Even after manually installing MicroPython 1.18 onto the Pico. Been trying to fix this error for 2 days now.
I ... actually did not know that about the plotter thing... huh... does that only work if you do the { } stuff for the print statement? Aka, can I just use simple concatenation instead of { } ? (It's not a problem, I can start using { } , but my brain just default's to concatenation XD )
It works for regular printed messages. (Regular in the sense that the format is unchanging). Just make sure to only print one message per loop. Thonny will detect the format and put in the plot labels automatically. So, yes, it will work for concatenated prints too!
can anyone help me with the pico. It keeps rebooting everytime i try to install micropython in it. also even i do not press the bootsel button it still opens as a removable drive
Hey Troy, the Pico W uses pin 25 for its wireless chip, so now you control the led pin with "LED", instead of 25. Old Line: led = Pin(25, Pin.OUT) New Line: led = Pin("LED", Pin.OUT) This should work for all Pico variants as well.

I here repeat your question: "from machine import Pin" when I run this, it say cannot find module 'machine' Any solutions ?
I think I had the same thing happen, you have to change your interpreter. To do that, under "Run", select interpreter and change it to Pi Pico. If you dont have that option, in the top right there should be a line "change to default" or something like that. Press that, restart Thonny and you should have the option under run. Hope that helps
I get "Couldn't find the device automatically. Check the connection (making sure the device is not in bootloader mode) or choose "Configure interpreter" in the interpreter menu (bottom-right corner of the window) to select specific port or another interpreter.%Run -c $EDITOR_CONTENT". So at what point do I unplug and replug the Pico ? I assume that I'm still in "bootloader" mode until I do ? Even that does not work, so where to go from here. This device appears to be so new to the market, that no one has released a TH-cam video that fully explains the pitfalls.
