Description
Hobbyist electronics can be a fun way to learn new skills that can be helpful to your career. Those who understand the basics of electronics can design their own circuits and projects. However, before you run, you need to learn to walk.
It all starts with analogue electronics. You should be familiar with the simple components and circuits and understand their basic behaviors and the issues you may encounter. The best way to do this is through real experiments. Theory alone is not enough. This book offers a large number of practical entry-level circuits, with which everyone can gain the basic experience.
Through the widespread introduction of microcontrollers, a new chapter in electronics has begun. Microcontrollers are now performing more and more tasks that were originally solved using discrete components and conventional ICs. Starting out has become easier and easier thanks to platforms including Bascom, Arduino, micro:bit. The book introduces numerous manageable microcontroller applications. It's now a case of less soldering and more programming.
