Includes Mini Motor, E-Tech Module, Sensor, Lightbarrier, Magnetic Sensor and Buzzer, and battery tray for 9V block (Battery NOT included)
STORAGE SUGGESTION: with each PROFI E-Tech set we recommend 3 Sorting Box 500--258x186 (#94828) with dividers and 1 Base Plate 258x186 Cover (#32985)
Specific concepts addressed with this set: Electrical engineering and electro-mechanical automation of systems without a computer.
Electric Circuits—interrupted circuits and closed circuits.
Build a model of a Torch/Light, and experiment with using the pushbutton as either a make or break contact. Do the same experiment with the Refrigerator Model.
Circuit Diagrams—learn the components used, and draw diagrams for each of the models you work with.
Conductors and Non-Conductors.
Build and experiment with a Continuity Tester.
Series and Parallel Connections—learn about and experiment with these.
AND-OR Circuit--Build and diagram an AND-OR Circuit, and experiment with both series and parallel connection variations.
Two-Way Connections---build a simplified model of “staircase lighting” to learn how this works by using a change-over switch, aka commutator.
Electric Motors and Polarity—learn the functional principle of an electric motor.
Build a model of a working elevator to study the principle behind a motor control with two directions of rotation.
Electro-Mechanical Controls—Build a flashing light control and a traffic light control.
Controls Using Electronics/Microprocessor Control—learn about a microprocessor system and programs Learn how magnetic sensors work by building a model of a safe door with an alarm system using such a sensor.
Learn about phototransistors and utilize one in building a model of a working hand dryer.
Do further experiments with a microprocessor and sensors by building models of a punching machine, automatic garage door opener, parking garage barrier and a brick dispensing.
