The full guide: core-electroni...
Now that we can connect our Raspberry Pi Pico to the internet, it's time to control something! This guide will cover setting up a server to host a simple page on your network. We'll use this page to control some hardware attached to our Pico W - drive an LED and read the status of a button. Once we master these inputs and outputs, the sky is the limit!

Great starter video. I really appreciate the basic web server. Just the basics. Nice not having to learn Flask (or whatever) first. Read a pin from the board. Read input from the web. Change an output on the board. Write something out to a web page. That gets me started. Exactly what I needed. Feel I can take this and run with it. Thanks

Great tutorial, thanks! Just a heads-up that there are a number of web serving libraries which could make the work easie...my favourite is microdot which is inspired by Flask and the decorators used to configure HTTP endpoints. Please keep the MicroPython videos coming! (I'll be mentioning this one at the Melbourne MicroPython Meetup tomorrow!)

I did a quick search on your videos and I did not see a video for a Pico W setup as a stand alone AP/WebServer. This video looks as if the Pico W will log into the home network and then the user will access the the Pico w through the home network. A stand alone Pico W could be a GREAT future video. Maybe even utilizing the Push button/LED project for that video also. Just a thought. Outstanding Video!

A good tutorial that gives a basic web interface for the Pico. Other videos I've watched cover Flask but in a full blown Python/Pi 3/4/zero context. It's good that you get to see results from code that you can follow along with. Will experiment with my Piicodev OLED, Atmospheric sensor, and Li-ion battery. Hopefully capture data to a CSV file and create a remote data logger.

That was a really useful tutorial! Would you consider doing a tutorial on combining a Pico w web server with a BME280? I've been programming in C for years, and I am now starting to learn python, and I think a project like that would be good one to learn how to remotely read sensors.

This will only work for a Pico W Microcontroller, not Raspberry Pi's single board computers. We don't have a guide on it unfortunately (thats a good idea though), but you can find others along the lines of "Rpi Zero W host HTTP Server"

This video brings another thought/question. I'm currently using a Rpi0W as a control server for my Rigol DM3058e, thanks to your video on making the Rigol stuff talk to each other. I have the PSU and the DSO on LAN but the DMM only has USB-B. The Rpi0w is really a waste of resources for running simple webserver for control/datalogging. I'm wondering if a Pico with a webserver would handle that small function. Only tricky part is the USB connection.... Can it be done?

Great video as always from Core Electronics. I am trying to implement a pico w with an LDR sensor that logs time and date to a CSV file when my central heating comes on and goes off. I have all that aspect of the project working just great but I want to be able to download the CSV file from the pico via a link on a web page. I am very close but I am unable to download the file, any file, and I cant find out why or how to do it. It seems like it should be such an easy thing to do. All the examples of webserver functionality seem to focus on LED manipulation. Who needs to turn on an LED over the internet? I would really appreciate any help or info on how I can achieve file downloads over my LAN. Thanks in advance.

@eezees9306 Год назад

Thanks for this, I find your presentation well paced and easy to follow. I am trying to re-program a garden watering system to include a wifi connection. All the examples of Pico W web servers I've found involve an infinite loop for the server. What I need is code running the watering system to run with the server in the background. The server traffic will be minimal.. just me on the LAN occasionally. I'm not sure if I should try to use uasyncio or just run through the server code every few cycles to see if there is incoming requests. Any advice?

@MichaelKingsfordGray Год назад

The RP2040 has two independent cores. You can run the server on an infinite loop, and have the other core handling I/O, along with the help of the 4 independent PIO cores, if required. A very powerful little chip.

@BambooInc Год назад

Thanks! This was a great tutorial for my first Pico W project. I took an additional step and set up port forwarding on my router to allow access from a public IP address using a specific port. That worked great, until I had different users try it from different locations and some had trouble connecting until I reboot the pico. Maybe it gets stuck on a connection session with the first person to connect? Could this be solved if we end the connection with the logged in user after X minutes of inactivity so that the server is waiting for a new connection without a reboot? I'm new to python - any suggestions are welcome.

Interesting stuff, are there any projects about setting up a stand-alone webserver to serve webpages (without being connected to the Internet)

@Core-Electronics Месяц назад

I'm a little confused about what you are looking for, this method should work even if your local wireless network doesn't have internet. If you don't want to use an existing wireless network, we have a tutorial on how to make the pico serve a webpage over its own network that it hosts! core-electronics.com.au/courses/raspberry-pi-pico-workshop/#5.3-hosting-a-wi-fi-access-pint-and-web-page

@TheCeredigion Месяц назад

@@Core-Electronics Thanks for the response, I'll have a read through. I think that's what I was looking for. Something really simple, (like a wifi hard-drive) but where you can just link to the wifi coming from the Pi and it takes you to a webpage and lets you access the content (as web pages). Be great for workshops in the middle of nowhere, or camp sites or could provide info in isolated places.

I think this is way too much to handle for the Pico, you might need a Raspberry Pi 3 or 4 (or any SBC for that matter), not a microcontroller for this, as you need to handle authentication and file upload

Would I be able to use a Raspberry Pi Pico W as a Backup DNS Server to keep my Internet Online if my Raspberry Pi 4 goes Offline? My problem is my Router makes me put in two DNS Addresses so I set them both as the PiHole DNS Addresses I've tried setting the Secondary DNS as Google's DNS but if I do that and turn off my Raspberry Pi 4 it doesn't allow me to connect to the Internet unless I turn the Raspberry Pi 4 back on and with the Prices of Raspberry Pi 4 and even the Raspberry Pi 3 right now I don't really want to spend that amount of money on another one right now if I don't have to?

@Core-Electronics Год назад

This is a necessary constraint of PiHole - blocked queries *need* to fail. It's worth a shot! sounds like an interesting project. The trouble will be keeping the DNS tables synchronised between devices.

@sivaasapu4580 Год назад

sir, On the Raspberry Pi 4 model, is it possible to run two programmes at the same time?

@Jo-re2ye 16 дней назад

Even 10, but this about the pi pico. Here to you can run multiple processed as it has 2 cores, or you can use uasync library for cooperative sharing of a single core. There are also 8 state machines, but those are a bit trickier to program. It's a really powerful little device

@viliamholub509 2 года назад

I’m nitpicking little bit here, but query in GET should not change state. It is supposed to be idempotent. To change state, use POST. Nice demo anyway

@edwinrivera5128 Год назад

I realized that if you put these pin numbers in here: led = Pin(16, Pin.OUT) button = Pin(15, Pin.IN, Pin.PULL_UP) the light gets dimmer, as if the voltage coming from over there is too low and that makes it reach less to the LED light. don't know if that's true but I'm still figuring things out.

Hi Mike, Pi Hole is an application that is designed for Linux based systems, so it won't run on a Pico W as it is only a Microcontroller and not a complete computer. It may be possible to create an ad blocker that runs on a Pico W but we seriously doubt its efficacy when compared to a Raspberry Pi running Pi Hole. Thanks for the question 🙂

@edkhil Год назад

@@Core-Electronics So why did you even leave the "192" in the first place? It would have made more sense if you censored your whole IP, right? Also, I don't think revealing a single *local* IP address could do any harm or give something away about your network, except the address range (which you already pretty much revealed).
