traffic lights! This innovative Lab Manual uses projects and examples that are based on everyday automated control systems to provide readers with a clear understanding of the "hows" and "whys" involved in the use of latches, timers, counters, sensors, relays, and more. A comprehensive introduction to ladder logic diagrams and PLCs sets the stage for more than 50 project-based lab exercises that effectively expose users to a number of control situations for active, "hands-on" learning.
