What should I include when going into detail on projects on my portfolio?

I’m currently working on my projects page for my portfolio and I just simply don’t know what to talk about. The projects are quite straightforward, for example here are a couple : my twitch API project and my calculator. They didn’t require very much planning and I didn’t run into any big obstacles.

I could talk about their visual design, but I don’t think of myself as a designer and so I don’t want anyone viewing the portfolio to get the wrong impression. I do plan to do a bullet point list of technologies used in my projects, but that isn’t substantial enough.

What would my fellow coders recommend?

Just describe what features you implemented and what technologies you used.

make it a scientific calculator?
