The Mini Lab Electronics experimental kit offers a hands-on introduction to basic circuitry. Using solder-free components, six different projects can be built, including a working alarm system with a light sensor and buzzer. The individual components are securely connected via push-fit contacts, meaning no soldering is required. An illustrated, multilingual manual guides you step-by-step through the various experiments and explains how the electronic components work. Two LR06 batteries are required to power the circuits.
