Information
The Arduino MEGA has 16 analog sensor ports and 53 digital sensor ports.
Analog: No Sensor - No Sensor Attached. Pin is disabled.
Potentiometer - Standard Analog Input (0-1023), no modification to raw value.
Light Sensor - Standard Analog Input (0-1023), no modification to raw value.
Line Follower - Standard Analog Input (0-1023), no modification to raw value.
Gyro Sensor - Support for VEX Gyro Sensor. See documentation here.
Accelerometer - Support for VEX Accelerometer. See documentation here.
Digital In - Use an analog pin as a digital input (not currently supported)
Digital Out - Use an analog pin as a digital output (not currently supported)
Digital:
No Sensor - No Sensor Attached. Pin is disabled.
Touch - Digital Input for touch sensors. (reversed from "Digital In" command)
Quadrature Encoder (Two Pins) - Support for VEX Quadrature Encoder. See documentation here.
LED to Vcc - Pin configured as digital output with reversed logic (for LEDs) (0 = LED on, 1 = LED off)
Digital In - Pin configured as digital input with internal "Pull-Up" resistor enabled.
Digital Out - Pin configured as digital output.
Digital High Inpedance - Pin configured as digital input without the "Pull-Up" resistor enabled.
Sonar [Ping] - Support for Parallax Ping Sonar Sensor (returns distance in cm, mm, inches, raw)
Sonar [SRP-04] (Two Pins) - Support for VEX Robotics Sonar Sensor (returns distance in cm, mm, inches, raw)
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.

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).
