RPi Pico Microcontroller

Anyone having a "dabble" with the recently introduced RPi Pico Microcontroller?

As a self confessed RPi enthusiast and "dabbler" who has every model of RPi produced, couldn't resist getting one at the unbelievable cost of £3.60 + P&P!
Currently just playing around with Micro Python via "Thonny" on Win 10 desktop PC, this interface of course can be achieved perfectly well with any RPi model, Mac or Linux platform.

Considering applications, lots of information available on line, great little toy.

I'm a little disappointed it doesn't have 640K, purely for the amusement factor of having such a cheap tiny device with as much RAM as early PCs.

In all seriousness though, those specs are insane for the price, I'm just not sure what I'd use it for.  I was dabbling with the ESP devices but they are a PITA to work with and the software triggers the virus scanner.  If this had WiFi it would have been an ideal replacement, as I just wanted to build a few wireless temperature/humidity sensors around the house for cheap.

Yes, absolutely unbelievable at the cost, would struggle to get a cup of coffee and a cake for that!
I like the 3 X 12 bit ADC's, suitable for all sorts of analogue input applications.
Received 2 cheap miniture OLED displays today, going to have a play around with driving these from the Pico.

For anyone looking for a basic overview of the Pico this is very good:

Use this handy breadboard kit with the Pico:

As with all toys, one thing is inclined to lead to another!

Edit: Terminology correction.

I have a few OLED displays knocking around myself that I was also going to use on those sensors, but I could never get them to work.

I'm not great at coding, mostly a copy/paste/hack hobbyist.

and guided by this tutorial:

found it quite easy to get the displays working on a breadboard either in parallel on the same I2C port or individually from separate I2C ports of the Pico, very basic programming but certainly a start in project development.
