Rather than returning a raw value of 0 to 1023, ROBOTC will interpret the data from the "SensorType" and return a more accurate representation of the sensor's data. An example of this is the Light Sensor, which will return a percentage value from 0 to 100.

Information

The Arduino MEGA has 16 analog sensor ports and 53 digital sensor ports.


SensorType

TSensorTypes SensorType[tSensors sensor]
(TSensorTypes) The SensorType array is used to specify what type of sensor is connected to a certain port. Most users should not have to use this functionality and should use the Motors and Sensor Setup instead.


Parameter Explanation Data Type
sensor A sensor port or name tSensors


SensorType[sonarSensor] = sensorSonar;  // set 'SonarSensor' to be of type sensorSonar (the Motors and 
                                        // sensors Setup screen does this for you in the background)


SensorValue

word SensorValue[tSensors sensor]
(word) This array value will return and modify the value of the sensor. When a pin is set as an "input" the SensorValue array command will return the value from the sensor attached to that pin. When a pin is set as an "output", the SensorValue array can be written to set the output value of the pin (typically Digital Outs will be set to 0 for Low and 1 for High).
Parameter Explanation Data Type
sensor A sensor port or name tSensors
while(SensorValue(touchSensor) == 0) //Loop while robot's bumper/touch sensor isn't pressed in
{
   motor[rightMotor] = 63;   // Right motor is run at half (63) power forward
   motor[leftMotor]  = 63;   // Left motor is run at half (63) power forward
}
