Students read a step-by-step approach on how to connect a voltmeter to a circuit when making a measurement.

Learners consider the correct type of pushbutton to use as a Stop button, the way the Stop button should be hard wired, and the PLC input instruction to use. This animated object includes a short quiz. It is recommended that learners review the learning object “The PLC Examine-Off Instruction” before beginning this object.

Learners analyze an emitter-biased npn transistor circuit. A "help" screen is available.

Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.

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

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

Learners examine the fundamental concepts of sequencer output instruction. A simulated example shows a sequencer in operation.

In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.

In this simulation, learners follow a series of steps to operate the Marvel Saw PCII in the manual mode. This activity includes a video clip.
