Potentiometer (Black) component

Potentiometer with black plastic knob. Pointer colour can be changed in component properties.

Note: The default Vref properties for AVR/Arduino is AREF. If there is no voltage being applied to the AREF pin, then you must change Vref option from AREF to AVCC

Potentiometer Example

Property reference

	Properties
	Simulation
	Start Angle
Angle the control points to at its lowest setting. Measured counter-clockwise from the positive x-axis.
	Sweep Angle
Angle through which the control sweeps as it turns from minimum to maximum.
	Color
Colour of the pointer.
	Scope Traces
Selects if the scope traces are automatically generated or not
	Retain Value
If yes is slected After saving your project, the ADC value will be retained when your project is reloaded.
	Connections
	Channel
Analogue input channel - which pin is the analogue input conected to?
	Settings
	VRef voltage
Used by the GetVoltage or GetString component macros to take an ADC reading and convert it into a Voltage. +VRef voltage x 10mV Default 500 = 5.0V
	VRef option
Defines what is used as the ADC maximum reference. ADC Range = GND to VRef Voltage. VDD - Defines the microcontrollers power supply pin as the max reference, VREF+ Pin - Dedicated pin on the microcontroller to allow for a variable reference voltage.
	Conversion speed
Clock setting to select how fast the ADC peripheral will perform an ADC conversion. The FRC setting is based on a RC time base and so will vary with temperature and pressure. Other settings are generally based on divisions of the master clock.
	Acquisition cycles
Number of micro seconds to wait for the ACD input to charge before starting the analogue sample.
	Bit Depth
Maximum number of digital bits the ADC can sample. 8 bit = ADC range 0 - 255 10 bit = ADC range 0 - 1023 12 bit = ADC range 0 - 4095
