In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.

Learners follow steps to trace logic signals from the inputs of several interconnecting logic gates to one output.

In this animated activity, learners examine the fundamental operation of a logic probe that is used to detect logic signals in a digital circuit.

Learners will identify ladder logic diagrams and the logic functions they perform.

In this animated object, learners examine how to use a programmable logic controller as an alternative to hardwiring a ladder logic circuit.

In this animated object, learners follow a process for troubleshooting digital integrated circuits on a printed circuit board using a logic probe.

Students view the layout and operation of a digital logic probe.

Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.

The schematic symbols of logic gates used in digital circuits are shown.

In this learning object you'll become familiar with the Hurco Controller in full CNC mode.

In this learning activity you'll practice operating the Hurco Controller in the CNC mode.

In this learning activity you'll review an explanation of how to operate the Hurco Controller in the manual mode.

Learners view an animation showing the one-shot operation of a programmable logic controller.

This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.

Learners examine eight different kinds of faulty logic or perception that interfere with critical thinking. They are superstition, ignorance, clustering illusion, false analogies, gambler’s fallacy, irrelevant comparisons, post hoc fallacy, and slippery slope fallacy. In an interactive exercise, learners identify ways to overcome these barriers.

In this animated object, learners examine the types of information to enter, and the sequence of steps required, to program a programmable logic controller (PLC) timer.

The learner will understand the operation of the six fundamental logic gates and the inverter by using truth tables, Boolean Algebra equations, switch analogies, and written statements.

Students review the functions of the keys on the Starrett HB400 Optical Comparator controller.

Learners examine the functions of the three types of memory used by an Allen-Bradley SLC-500 programmable logic controller: the Executive ROM, Scratch Pad, and Processor File.

In this learning activity you'll examine how logical addresses work. The IP address is the logical address assigned to a connection by the ISP or network administrator.
