Simplifying Electricity About Locktronics automotive
What is Locktronics? Locktronics is a range of products that simplifies the process of learning and teaching electricity and Electronics
Subject areas we focus on Science Electronics / Engineering Technology Automotive
The range consists of more than 200 items Baseboards Inductors System blocks Active subsystems Resistors Semiconductors Electromechanical Optoelectronic Capacitors Logic gates Curriculum packs Accessories
How does Locktronics work? n n n Review curriculum Take a base board Follow instructions on worksheets Add components Learn through experimentation
Unique benefit of Locktronics As students construct the circuit they can see the circuit diagram. This helps students link theory to practice and simplifies the learning process.
Why choose Locktronics? Components identifiable under carrier Spring clips riveted on for strength Circuit symbol bonded onto carrier Component value easily identifiable Strong soldered joints Durable, robust plastic carriers are long lasting and cost effective Simple repairs can be made in-house n n n Makes learning easier Saves preparation time It lasts and Lasts Versatility Support Most up to date circuit symbols now available Custom made metal clips can be bent many times. Rust proof springs ensure good connection

Automotive in more detail
Methodology in automotive - starting n n Students are advised to study Electricity, Magnetism and Materials before going on to advanced courses. Students understand symbols, circuits, wiring, and theory Students must get involved in wiring circuits Students progress through ‘traditional’ subjects such as AC etc.
Methodology in automotive – sense and control Students understand: n systems and ECUs n Circuitry inside an ECU wiring n How software makes open and closed loop systems n Circuit configurations n Students work in pairs n Students build circuits with 5 or 6 wires
Methodology in automotive – CAN bus Students: n Wire up each node n Test each node n Students work in pairs or groups of 4 n Each circuit contains up to 14 wires
Methodology in automotive – CAN bus Students wire up the whole system and use the admin /scan node to discover how the system works. This looks very difficult But students build it slowly and gain confidence in wiring
