Raspberry Pi ☛ Designing patterns for your Christmas lights
In last month’s issue of Raspberry Pi Official Magazine, we looked at different forms of WS2812B LEDs (also known as NeoPixels) that you can use to make Christmas lights. Now, let’s take a look at how to customise them. We’re not going to dwell on the software too much — there are libraries available for just about every language you’re going to come across, and you can control them on a Raspberry Pi, a Raspberry Pi Pico, or most other platforms that you can physically access a GPIO on (we’ll use CircuitPython on Pico, but you could translate it into another language or platform fairly easily). Instead, we’re going to think about what we want them to do. In other words, rather than looking too much at how to make them work, we’re going to focus on how to make them look good.
