Detailed Description

Touch-sensor interface (passive mode).

The Touch Sensor Class - using a touch sensor in passive mode

At construction time you specify the RCX connector pad to which the touchSensor is attached.

Note:
TouchSensor is implemented as a simple redefine of the Sensor class (saved ~48 bytes per instance). See "list of all members", above, or refer to the Sensor class for all methods
See also:
The other sensor classes: Sensor, LightSensor, RotationSensor

Definition at line 44 of file TouchSensor.H.

Member Enumeration Documentation

enum Sensor::Port [inherited]
 

List of sensor identifiers (IDs). Possible Sensor Port Values.

S1, S2, S3 are connector pads 1, 2 and 3 on the RCX.

Battery is the internal sensor allowing a program to read the current battery voltage in milliVolts

See also:
Battery
Enumeration values:
S1  RCX sensor port 1.
S2  RCX sensor port 2.
S3  RCX sensor port 3.
Battery  RCX battery sensor.
