Conduct and understand your own electronics experiments. Everything about electricity, circuit diagrams, charges, and voltages. With many tricky questions and tasks at the end of the chapters. Batteries, switches, lamps, motors, and LEDs are part of our daily lives. In this book, Florian Schäffer not only imparts technical background knowledge and hands-on physics but also experiments, builds, and measures circuits with you. Lemon batteries, Morse switches, dimmers, light barriers, lie detectors, skill games, flower watering machines, and much more await you. All experiments are clearly described and richly illustrated, making it easy for you to replicate them. In a relaxed manner, you will learn what electricity and voltage actually are, and then you will be able to professionally decipher circuit diagrams and develop your own experiments. Important electronics mnemonics, simple formulas, and the most essential concepts are included.
