New Raspberry Pi Pico W - Micro controller with Wireless Wi-Fi networking

I’m excited to see that there are now two new versions of the Raspberry Pi Pico – the Microcontroller from the same people that brought you the credit card sized Linux computer costing $35.
The Raspberry Pi Pico came out about a year and a half ago. It’s a microcontroller based around their own designed RP2040 chip. It is easy to program in both C++ and MicroPython. I’ve used it for a few different projects myself.
I’m going to introduce the new models and at the end of this video there will be a quick example of how you can use the new Pico W as a voltmeter.

When the Pico was released the one thing it was lacking was connectivity, which has restricted it’s use. At a time where everything is going on line it was frustrating not being able to connect to the Pico using WiFi. There have been some ways of getting the RP2040 to connect to a wireless network. The first is to use a board which combines the RP2040 and an ESP32 wireless module. This is exactly what Arduino did and I used that for a port of my Wireless Pixel Server project. Another is to combine a Pico with an external ESP32 which is something I used with the Pimoroni Pico Wireless Pack. You could also pair the Pico with a Raspberry Pi computer, which is something I’ve demonstrated using Uart, but also available using SPI or I-squared-c.
This has now changed with the new model, there is now a Raspberry Pi Pico W, with the W standing for Wireless. It allows you to connect to a wireless 2.4Ghz network and opens up the Pico to the world of IoT.

This video shows a wireless version of the Rasperry Pi Pico Voltmeter that I created in an earlier video.

Was given a Pico W by my supervisor for my personal project in my 3rd year. Looking at what it can do and what it can't do, stumbled on your channel by the Algorithm gods, thank you for the simple setup :) Hopefully using it for water quality monitoring

Great addition to the Pico range. The 2040 connect for me still has two big advantages, more memory and being Arduino compatible. I am sure the later will follow soon and the lower price will balance the first.

Say I have 3 analog sensors I need to get info wirelessly from. I need that info to go to the primary Rpi 4 to appropriate pins for processing. How to best communicate between them? Nicely done video.

Do have any idea, about the power consumption for the module with Wireless on, when using a battery??

Witch language is the easiest to learn ? C++ ?

Hi, Would you be kind enough to explain step by step to a neophyte how to use a Pi Pico W as a wifi router for a very old printer.THANKS

"C++ and MicroPython"

And rust 😉
