The LEDs learning package offers tinkerers a quick introduction to LED technology and therefore to electronics in general. All you need is a fresh battery (9 V) and off you go! Numerous impressive experiments can be carried out with LEDs and resistors alone. Many of the home-made devices have a lasting practical use: Colorful and white LED flashlights as well as test devices and sensors can be built with them. The experimental system can also be expanded as required. Additional components such as transistors, capacitors and integrated circuits can also be used on the plug-in board. The enclosed 'Quick Start LEDs' manual provides circuits and construction plans for simple and more sophisticated projects.
