Those based on the ATmega8, for example, have about 8KB of Flash memory, of which the Arduino firmware takes up about 1KB, leaving 7KB for user programming. And RAM is limited to 1KB on those. I guess it comes down to what the class of ordinary micro-controllers is.

You can load an Arduino stack and program them as Arduinos, but you can also go bare-bones and just use C to do your own thing (in which case there’s somewhat more memory available plus access to more interfaces, at least on some models). It was also the Teensy that introduced me to easy to program (via USB interface) and easy to interface via USB human interface device (HID) functionality in a micro-controller. Things have come a long way since the Motorola MC68HC11 days.

But, yeah, a DIY micro-controller book with a more holistic approach to a complete project is a change for the better.

I assume that is generally true. There is a range of processors out there, micro-controllers, and I think they generally use some sort of code. Something like the Arduino probably has more room than the average microcontroller because it is a prototyping system.

I work in a company that helps innovators develop new products and my brother’s actually a coder. So I was pretty blown away to read this article – and if I’m right, which is by no means certain – it means that our everyday products are using a computer language.

This has given me so many ideas. Thanks for a really interesting article.

It is, however, more correct to say that it uses C++, since that is the language actually used by the arduino ide.
