I love Christmas decorations and lights, and I'd been wanting to do an programmable LED project for a long time. Recently, I built a light array made of LED lights, ping pong balls, and a Raspberry Pi Zero. I thought it was worth sharing, because it ended up being relatively easy but also educational.

So if you are looking for a more portable way of interacting with C libraries, consider using the ctypes module.

This article doesn't cover hashmaps, but you can read all about them in my Using a hashmap in Java article.
