The much-anticipated new edition of ''Learning the Art of Electronics'' is here! It defines a hands-on course, inviting the reader to try out the many circuits that it describes. Several new labs (on amplifiers and automatic gain control) have been added to the analog part of the book, which also sees an expanded treatment of meters. Many labs now have online supplements. The digital sections have been rebuilt. An FPGA replaces the less-capable programmable logic devices, and a powerful ARM microcontroller replaces the 8051 previously used. The new microcontroller allows for more complex programming (in C) and more sophisticated applications, including a lunar lander, a voice recorder, and a lullaby jukebox. A new section explores using an Integrated Development Environment to compile, download, and debug programs. Substantial new lab exercises, and their associated teaching material, have been added, including a project reflecting this edition''s greater emphasis on programmable logic.
