Complete electronics kit for testing and experimenting. No extensive prior knowledge is required. Illustrated instructions for 12 exciting projects. Includes all components, circuit board, and manual. Components are pre-soldered. With this learning package, you will build a fully equipped experimental system that allows you to acquire or deepen your knowledge in semiconductor circuit technology. The components are pre-soldered; only the connections need to be plugged in, and you will have a fully functional circuit. Comprehensive manual. The manual is easy to understand and illustrated, making it perfect for beginners. It explains the assembly of the projects step by step, making practical implementation straightforward. The projects can be quickly and accurately replicated. And even if a mistake occurs, it is not a problem thanks to the built-in current limitation. You can build the following projects yourself: alarm system, flash light, delay control, electric field sensor, light sensor, constant current source, good night light, touch sensor, touch dimmer, evening light, RS flip-flop, and turn signal.
