LED inclinometer with FastLED and Analog Devices ADXL345
You’ll learn how to make an interactive spirit level or swell meter. How to calibrate, read and de-noise an acceleration sensor; driving an LED strip with Arduino and FastLED.
While the electronic circuit is usually very straightforward, the “magic” in physical computing projects happens always in the code. So, please see the GitHub link to the BOM, the schematic, and extensively commented code that you can easily adapt and recycle in your own projects. Often, there’s a useful code concept or code snippet that you can use for an entirely different design, because it’s a fundamental principle.
If you want to learn about good soldering, this seven minute vintage video is still the best of them all.
