A long time ago, I released a series about real-time programming on a BeagleBone Black. I then decided to use the BBB to control the CRT display of an old Macintosh Classic computer. As you can imagine, I was thrilled when the new Arduino Nano series with built-in real-time capabilities was announced and in this article, I’d like to revisit the old topic and discuss what has changed over the years.

I finally came around finishing this project and I also made a video in which I explain the build and also show you how to assemble the project. This article covers the case design and some changes in the source code in more detail compared to the video.

Shift registers can be used in a wide variety of applications. You can, for example, use them to convert multiple parallel data lines to a single serial line and vice-versa. This technique can be used to extend the number of available in- and outputs of a microcontroller and this article will show you how you can achieve this.

More than often enough parts of projects will have to communicate with each other or external devices. This can either be done by directly connecting the devices with cables but sometimes it’s more convenient to wirelessly connect the different pieces of hardware. This article will show you how to use the ESP8266 and it also includes two examples for using it with a Raspberry Pi and Arduino boards.

Some Arduino boards have a built-in EEPROM that can be written to and read from in your programs. I not only want to discuss how that’s possible but I also want to show you an alternative while talking about EEPROMs and memory in general.

I wrote this series about the basics of programming in Java quite a while ago and I got asked to write another one about the basic concepts in Java, Python and C.

When you build custom projects you eventually get to a point where you want to design a custom case for your product. If you are not interested in learning complicated and expensive CAD software, Tinkercad is the way to go. It’s super easy to learn and to use and it has all the basic features needed for designing custom enclosures for your electronic projects.
