I am in the process of updating my book "Electronics Explained," published by Newnes/Elsevier. The book is essentially a basic electronics text for those learning about electronics for the first time.

This demo is implemented on a custom hardware (see Figure 1) equipped with a STM32L476VG microcontroller [1, 2]. The microSD card is connected to the MCU over SDIO interface. The implementation uses ...
