Cool! That is a great way to start. If you look at the Crowdsupply page, for $32 + shipping you can get the Pico and a set of 'shields'. The interesting one for you would be the "Grove" shield. "Grove" is a connector / pinout standard that was created and supported by Seeed Studio (see: https://www.mouser.com/new/seeed-studio/seeed-studio-grove/ https://www.mouser.com/new/seeed-studio/seeed-studio-grove/ for a video on the infrastructure and ideas behind Grove (also see the Seeed wiki here: https://www.mouser.com/new/seeed-studio/seeed-studio-grove/ https://www.mouser.com/new/seeed-studio/seeed-studio-grove/) There are a LOT of different boards you can get with sensors and what not on Grove and programming them in Micropython is supported because that is what Seeed uses (calling it Ardupy). You will have to solder the pins on the Pico and the Grove shield, but after that you can just plug them together with cables. Grove typically uses either a GPIO (on/off), and analog I/O, or an I^2C per board. You will need to know enough about those to match up the boards with the right connector on the shield. And then its just programming. One of the things I've used when I've helped people learn about this stuff is to use the Grove temperature and humidty sensor and the NodeD1 (this is an early ESP8266 design that also runs micro python). A Python program that reads the sensor and then does an http GET on a web server with a CGI that records temperature and humidity. Control flow looks like this: while true: temp = read_temp() humid = read_humid() http.get("http://192.168.1.5/environment.cgi?t=" . temp . "?h=" . humid) sleep(10) The same web server has a page that uses D3 to plot temperature and humidity over time. Very simple and easy to do. (and yes you learn to read the temperature and humidity over i2c, and set the chip up to connect to the wifi hotspot)
