Making It with an API

I haven't been running much since spring break for a number of reasons, and I thought about making a tool that would help encourage me to run. I had an idea to make a screen showing the latest 3 (or so) running activities from the ITP running group on Strava, and I thought "Strava must have an API, right?" They do!

I tried making curl requests, but wasn't having any luck, I wondered if my syntax was wrong, or I wasn't getting the keys right or something... For some reason I wasn't getting anything back. Upon reading a little further, I realized I might hit privacy blocks, and several of the API examples on the Strava documentation site were also broken! So I scrapped this idea...

A simple project that I would love to have is a weather clock on the wall in the bathroom because I'm not great at checking the weather. If I can see the weather when I brush my teeth in the morning, I will be more prepared when I leave the house!

I also googled "most reliable APIs" and Accuweather came up, which seemed promising to me.

Referencing Tom's Making Things Talk HTTP AQI sketch for the Arduino, I was able to connect to Accuweather but I wasn't getting any messages back. This is what shows up when I try to print the message:

Am I doing this right?
