Raspberry Pi Pico W Mandelbrot Set
Stumbled across a Python script to run a Mandelbrot set in ASCII in Python so I thought I would see how it ran on the RaspberryPi Pico.
After tweaking it slightly from the source it ended up like this mandelbrot.py
This results in the following;

Raspberry Pi Pico W Temperature
Have been tinkering with temperature measurement using the Raspberry Pi Pico.
First with the internal temperature sensor and then using a TMP36 temperature sensor externally.
I wrote two classes to access these and return the reading.
Here is an example using the two sensors together temps.py
You will need to upload the two classes to the Pico first in a library sub-directory.
Here is how you would wire it up on a breadboard tmp36.fzz

Rasberry Pi Pico W OLED
Some components arrived from AliExpress recently so been able to play with an I2C OLED display with my Pico W.
Hello World Test
Code of this is here https://github.com/alastairhm/pico_w/blob/main/i2c_scan.py
And also used here to display the IP address after connected to the wifi https://github.com/alastairhm/pico_w/blob/main/wifi_oled.py
Next thing I’ve been playing with is internal and external temperature sensors, I will post about that soon.

Raspberry Pi Pico W
Just before Christmas I got a Raspberry Pi Pico W to have a play with.
Looking forward to using MicroPython to do some LED flashing and other things.
Started a repo on Github for it Pico W Repo
