Sim LabComponents
Meters, displays and labels
LEDs, lamps, displays, probes, motors, labels and the grading point.
Lights and displays
| Part | Behaviour |
|---|---|
| LED | Lights when current flows the right way. Use a series resistor. |
| Lamp | A bulb that glows with power. |
| LED Array | A group of LEDs. |
| Decimal Display | Shows a number. |
| Instruction Display | Shows instruction text. Used by processor-style example circuits. |
| Dot Matrix Display | A grid of dots. Pins X, Y, D, WR and CLR. You can set its width, height and colour. |
| Audio Output | Plays a signal as sound. |
| Analog Output | An output for connecting the simulator to other tools. Rarely needed. |
Meters and probes
| Part | Shows |
|---|---|
| Voltmeter / Scope Probe | Voltage. Also feeds a scope. |
| Ohmmeter | Resistance. |
| Ammeter | Current. |
| Wattmeter | Power. A second, older Wattmeter is also listed. |
| Test Point | Voltage statistics at a point: RMS, average, minimum, maximum, peak-to-peak, period and duty. |
| Data Export | Records values over time for export. |
| Stop Trigger | Stops the simulation when a condition is met. |
Motors
| Part | Behaviour |
|---|---|
| DC motor | Spins with the voltage across it. |
| 3-phase motor | A motor driven by three-phase power. |
Labels and drawing
| Part | Behaviour |
|---|---|
| Text, Box and Line | Notes and shapes to label your circuit. |
| Labeled Node | Joins points by name, with no wire between them. |
Grading point
A Grading Point is a pin that question authors place to mark where a circuit is checked. Students don't see it outside the authoring view.
