This course will become read-only in the near future. Tell us at if that is a problem.

Introduction to Circuits

The basics of series and parallel circuits

In this task you will recap the basics of series and parallel circuits.

Navigate through the presi for the basic information

Task 1

Do the quiz to see how you are coming on.


Task 2 - The Zombies Are Coming!


The zombie apocalypse has finally come to pass.  Design a zombie detection system that will alret you to the approach of a zombie.

Your house is surrounded by a fence but you need to leave gaps for transport to get in and out, so a circuit based system is your only choice (see picture below).

To do this go to and click run now.

Test your design ideas first including setting the current, resistances of any resistors used and the vltage of the power supply

When you are done, post it and link it in the comments section for peer review.
