HTML to Python to Arduino to LCD

Last week found me standing tall upon my shell script soapbox, shouting command line praises to all who would listen.

Thou ought direct thine output aftways, to-wards thine USB port of thee. And that is well and righteous.

Well, that still is the case. My latest project has made it glaringly obvious that sometimes a little Python script will render a whole bunch of shell scripting moot. Namely, parsing HTML. Let’s see a picture…

Well, as luck would have it, my go-to after my main go-to is Python, and this type of thing has been issue enough to warrant a library. BeautifulSoup. It acts to parse the HTML info into items, that can be smashed around as I see(med) fit.

My setup was simple: py script to snag my comments and write serial, Arduino sketch to drive a LCD and read/write serial. And a source of shade. And a WiFi signal to snag.

Check, check, check, etc. Video time:

Pretty slick…hit the fold for the code, as promised, and a summary.
