Color Matching with NeoPixels

I keep getting distracted by other projects and ideas, but I wanted to post a brief update on the footwell NeoPixels project. I’ve been working on the data structures and color patterns, but today I wanted to cover something simpler. For the time being I’m not planning on changing the color of the tC’s interior lighting, which is a nice burnt orange. I’ve toyed back and forth with the idea of replacing the tC’s cubby light and adding a few lights to the cupholders, which on a default setting should match the rest of the lighting. This gives us today’s…

NeoPixel Prototyping Board

While the final version of the footwell NeoPixel project calls for a long strip of ~60 pixels, most of my time is going to be split between programming at my desk and testing the pixels’ response to telemetry from the car.  I didn’t want to have to wrangle a large strip every time I wanted to test an idea, and I figured most of the patterns for the 60 pixel strip could be replicated on a shorter one. My solution is this small prototyping board.  It’s a 3D printed part with mounts for an Arduino Uno, a small breadboard, and a NeoPixel…

Footwell NeoPixels: The Plan

This is going to be the first big project documented from start to finish on this blog. I recently had the the idea to put some lights in the footwells of my car, a 2008 Scion tC.  There are a variety of kits available online that use standard multicolor LED strips, but I was never fond of the options available. For one, the control interfaces are clunky and scream ‘mod’.  Most of them use thin remotes, though a few have small control boxes attached directly to the LEDs.  I wanted a control switch that integrated into the car’s switch panel…
