When it comes to music or any audio which is reproduced by any electronical device, we usually never think about the whole process which stays behind the transformation of our audio files into a hearable audio signal. Everything starts with audio files, which contains a digital representation of sound. Digital sounds are essentially a sequence…

Electronic sensors are part of many digital devices that we use every day, such as our smartphones, computers, and cars. A sensor is a device that collects some information of any kind (usually a physical quantity), which a computing unit can then use to make any decision and interact consequently in the physical world. Some…

Modern technology offers several ways to electronically measure a temperature, with different kind of sensors or probes. Possible examples are termocouples, thermistors or digital sensors. All of them have their pros and cons, in terms of cost, temperature ranges and resolution. In this article, we are going to see a very cost-effective solution to measure…

STM32 Nucleo-64 boards from STMicroelectronics are very common evaluation boards which are often used by hobbists and professionists. Thanks to a practical board design and to the available tools, prototyping with a Nucleo-64 it’s a very stressless and straightforward experience. In this article we are going to see how can we use the on-board serial…
