	SetTarget
Set the object that you want to test for collision with. If this is not called, or is called with handle = 0, collisions will be tested against every panel object that has 'Solid' status. NB) Specifying an object will save CPU power!!
- HANDLE	Target
The object to test for collision with.
- VOID	Return

	ReadProximityByte
Get the current proximity reading as a digital value from 0 to 255. The 'Polarity' property will affect whether the signal increases or decreases as the proximity increases.
- BYTE	Return

	ReadProximityFloat
Get the current proximity as an analogue value from 0.0 to 1.0. The 'Polarity' property will affect whether the signal increases or decreases as the proximity increases.
- FLOAT	Return

	ReadProximityInt
Get the current proximity as a digital value, 10 bit or 12 bit based on your ADC capabilities. The 'Polarity' property will affect whether the signal increases or decreases as the proximity increases.
- UINT	Return

	Properties
	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 ADC input to charge before starting the analogue sample.
	Connections
	Analog Pin
	Polarity
The 'Polarity' property will affect whether the signal increases of decreases as the proximity increases. Rising - Increases signal as proximity increases Falling - Decreases signal as proximity increases
	Simulations
	Magnet Object
Select an object from the panel to act as the magnet that triggers the reed switch.
	Range
Distance within which the sensor begins to be activated. NB) This is measured between the centre of the proximity sensor and the centre of the target object.
	Timer Interval (ms)
Time in milliseconds between testing for proximity. Small time = Greater CPU load Large time = More like to miss activation if it is very brief.
	Scope Traces
Selects if the scope traces are automatically generated or not
