To save you the trouble of searching for datasheets of the components used in Electronics Projects For Dummies I've put together these links. After the datasheet name I've included the project chapter in the book where I used the component.

Even if you don't buy my book (that probably means you borrowed it from a friend) these components are worth checking out and these links to datasheets will make your electronics projects life easier.
