Tutorial Teaches You To Use Neopixels With Micropython

Addressable LEDs are wonderful things, with products like Neopixels making it easy to create all kinds of vibrant, blinking glowables. However, for those without a lot of electronics experience, using these devices can seem a bit daunting. [Bhavesh Kakwani] is here to help, with his tutorial on getting started with Neopixels using the MicroPython environment.

The tutorial flows on from [Bhavesh's] Blink example for MicroPython, and is aimed at beginners who are learning for the first time. It explains the theory behind RGB color mixing that allows one to generate all manner of colors with WS2812B-based LED strings, and how to code for the Raspberry Pi Pico to make these LEDs do one's bidding.

The guide even covers the use of the Wokwi simulation tool. This is a great way for beginners to test their projects before having to play with actual hardware. This is useful for beginners, because it's a great way to catch mistakes - is there a software problem, or did they push the soldering iron through the microcontroller? It's also a technique that pays dividends when working on more complicated projects.

Whether you're entirely new to the embedded world, or just want to learn the intricacies of talking to addressable LEDs and make sense of color mixing theory, this tutorial will serve you well. Before you know it, you'll be building glowing projects with the best of them!

DIY Nanoleaf LED Panels Offer Peace of Mind

Nanoleaf light panels are a popular product for creating glowing geometric designs on walls. However, for those that like to avoid IoT devices that integrate with big cloud services, they're not ideal, and involve compromising on one's privacy, somewhat. [Viktor] decided to build something of his own instead to avoid this problem.

The design is that of an equilateral triangle, which allows the panels to tesselate well. Each panel consists of two 3D printed parts. The black PLA base holds the WS2812B LED strips, cabling, and ESP8266 controller, while a white PLA cover goes over the top, which acts as a diffuser to spread the light from the individual LEDs. Each triangle contains 24 LEDs, and six triangles together consume around 1.6 amps when in use.

The benefit of the system is that it's not controlled from a company's cloud system, which can be shutdown at any time. [Viktor's] setup runs entirely independently, and can be controlled from a simple web page. Plus, there's nothing stopping him from modifying the code to use the panels for any purpose; commercial products like Nanoleaf don't offer anywhere near the flexibility of building your own.

We've seen others build their own smart lighting with similar techniques before, too. Video after the break.
