Learners examine the three steps of a processor scan cycle.
Internal Elements of a 555 Timer
By Terry Bartelt
In this highly interactive object, learners examine the internal elements of a 555 IC and their operation. Learners then test their knowledge in a variety of exercises.
Sine Wave Fundamentals: Practice Problem #10
By Patrick Hoppe
In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.
Waveforms of an SCR Circuit
Learners view waveforms at various locations of an SCR circuit controlling the intensity a light bulb. The waveforms are shown when the light is dim, at medium brightness, and at full brightness. A brief quiz completes the activity.
Transistor AC Analysis Practice Problem: Circuit #4
The learner solves for Zin(base), Zin(stage), Zout, and Av. A "help" screen is available.
The schematic symbols of logic gates used in digital circuits are shown.
The Logic Gates
Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
Sequencer Output Instruction for the SLC-500 PLC
By Craig Hemken
Learners examine the fundamental concepts of sequencer output instruction. A simulated example shows a sequencer in operation.
The Universal NAND Gate 2
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.
Marvel Saw: Interactive Programming - Manual Mode
By Dave Hoffman
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.
