Appendix B — Electrical Diagram Schematics 413

Summary

You can start understanding schematics in an afternoon. Everyone keeps references around
to remind them what the various parts are. Use these references to help you understand the
schematic. Often the references contain other similar schematics that help you out. If you’d like
to build your own circuits and draw your own schematics, find some parts you’d like to use and
search on the Internet for schematics that use them. Alternatively, find one of the many circuit
databases on the Internet and find a circuit you want to build. One pretty good site to browse is
www.discovercircuits.com/, which has over 23,000 circuits to look at. Two others are
http://web-ee.com/ and www.epanorama.net/, both of which also have tutorials,
datasheets, and forums to talk about electronics.
