The document describes 6 labs involving using LEDs, logic gates, counters, timers and displays to learn digital circuits and programmable logic controller concepts. Lab 1 involves using DIP switches to control an LED with logic gates. Lab 2 uses an SR latch for feedback. Lab 3 adds a counter and 7-segment display. Lab 4 tests LED patterns. Lab 5 combines a counter, reset/increment buttons and LED/7-segment display. Lab 6 adds a timer and delay functionality.
