Editor-in-chief recommends

DMX driver with Bluetooth
Earlier articles have shown that DMX is a relatively simple system. The use of Bluetooth allows you to realize an uncomplicated driver with almost unlimited possibilities, conveniently operated with the help of a smartphone.

Modular meters
It was only in this issue that there was a place for long-ago articles awaiting publication in the queue, discussing the properties and specificity of modular meters. Meters that are relatively cheap and can find a lot of interesting applications.

As part of the C language course, we deal with the very important issue - interruptions. We enter into their secrets and learn about the various unpleasant traps associated with them. And in the cycle "Around C language", we discuss the return of values and side effects that turn out to be the basis of the program.

Radio training ground and SDR radios
In the fourth episode of the Polygon, we "jump" to the modern SDR radio, bypassing the archaic types of radios. We are doubly convinced that the implementation and use of digital SDR radios is within the reach of every EdW reader.
