With the E-Tronic, the world of electronics can be discovered in a playful way. Simple circuits, series and parallel connection, electronic circuits with transistors, capacitors, resistors and LEDs. Step by step, this construction kit teaches the basics of electronics. The Electronics module, a controller with 16 fixed programs, has two motor outputs, three analog inputs for sensors and a potentiometer for controlling the speed of a motor. From simple to complex models such as an interchangeable turn signal, many exciting models can be constructed with this kit. For example, a garage door or a marble run can be constructed with exciting electronic components. The eLearning portal contains didactic information on the subject of electronics.
