Lesson 2: Scientists at Work
Students select an electronic invention and research who and what contributed to it.
Lesson 4: Using Transistors
Students build circuits to see how transistors function as switches or amplifiers
These Tutors which are Interactive as well are useful for Students and Enthusiasts to enhance the Text Book reading.
Electricity and Magnetism – Molecular Expressions
These pages are good for any person who want to be more familiar with magnetism and electricity. This probably means everyone. Today Electricity Basics is General Knowledge and also an Absolute Essential.
Interactive Java Tutorials – Covers principles, physics, and devices used in electricity and magnetism.
This site uses hands-on experiments to show the basics of how real things in the real world are controlled with computers.
Controlling The Real World With Computers
This site is also for anyone who is the least bit curious about monitoring and controlling such things as motors, lights and switches, or recording and playing everything from sound to the arm position on a robot.
Experiment 7 – Bi-directional Control Of Motors And The H-Bridge
It would be useful to be able to run a motor in either direction. That’s simple with a motor of the type that’s been used in the experiments thus far. Reverse the DC power connections on such a motor and its shaft will rotate in the opposite direction. One way to control direction is to use switches arranged in the following manner:
