Real-time simulations on an Arduino (double pendulum)

I got a small display compatible with my Due for christmas. And since I really wanted to see some arduino-in-the-loop simulations, I decided to use it for exactly this: real-time multibody simulations on the Ardunio and the results displayed on the tft.

DIY glowing lamp with shifting colors (Arduino-based and interactive)

This post is not really about multibody dynamics. Instead of simulating stuff, I’ve actually built something: A glowing, more-or-less-interactive lamp.

We are awaiting our first child and with all the things we bought (mostly used), there was a small, adorable lamp. Unfortunately, it had some weird-looking electrics inside (both looking very old and labeled for 120V – so it wouldn’t work with our 230V here in Germany), so we decided to remove all cables and replace them with LEDs. Actually, WE just decided not to use the existing cables and then I talked my wife into letting me build something with an Arduino.

So I hooked up the lamp with a digital LED-stripe – I found one that came with digitally-adressable LEDs and used the Adafruit Neopixel library to adress those. Now there are 24 RGB-LEDs inside the lamp which I can control direct with the Arduino.

Programming advice for an engineer: Get an Arduino

Until the beginning of this year, I’ve only been coding in Matlab, GNU Octave and a few other comparable high-level 4th generation programming languages. I’ve long wanted to learn a more basic programming language which allows smaller and faster programs (more on this in another post). Basically, I wanted an answer to the question:

I’m an engineer and want to learn about programming. What can I do to get started?

It turns out one of the best answers is this: Get an Arduino.
