As prep for future projects, I’ve built a simple 2D array of individually addressable LEDs. This canvas will ultimately serve as the platform for some games (snake, pong, etc), but I’m hopeful that other people will find this useful and come up with some cool applications.
LED strips are growing in popularity and ease of use. I’ve been playing around with them lately (with my Arduino), and, for the uninitiated, here’s an overview of what’s available, and how much it costs.
At Braintree, the developers get every other Friday to work on non-work-related projects of their choosing. Collaboration is encouraged, but even if you end up working on something alone, it’s a great way to spread your excitement about whatever interests you at the moment (and it’s a nice perk to the job).
This week, my project was to get some LED strips unboxed and working. The strips are flexible circuit boards, with full-color LEDs dotting one side. Each “LED” is actually three LEDs clustered together (one red, one green, one blue), and with 21 control bits, they can display more colors than the human eye can distinguish. I bought a variety of strips, with different features, and I don’t know exactly what I’m going to do with them, but step 1 is to learn how to use them.
