Electrical Engineering: Science Videos

This series follows hands-on robotics and electronics projects. You will see how to build a simple robot, how sensors detect light and motion, and how a small motor compares to the one inside a hair dryer. Demo videos show fun builds like a coin detector and a light guitar. There is also an introduction to programming. These projects show how engineers turn ideas into working machines.
