Arduinos:

arduino_analog_sensor_pinNumber = @;
arduino_digital_sensor_pinNumber = @;

pinNumber is the number of analog / digital input pin. The value of the observable is automatically updated when the input pin value is changed in the Arduino.

actuator observables are lists with pin number / pin value pairs:

arduino_digital_someIdentifier is [pinNumber, pinValue];

pinValue either 1 or 0 for high and low

arduino_analog_someIdentifier is [pinNumber, pinValue];

pinValue from 0 to 255 (PWM)
someIdentifier can be anything

arduino_servo_someIdentifier is [value];
hard coded to pin 9

arduino_dc_identifier is [PWMPinNumber, PWMValue, digitalPinOne, digitalValue,
	digitalPinTwo, digitalValue];

arduino_regulated_identifier is [PWMPinNumber, PWMValue, digitalPin, digitalValue];


When using the actuators, the plug-in listens to all changes of observables with arduino prefix so they can be used in for example like:

arduino_analog_sensor_5 = @; ## bind observable to analog port 5

reverseMotorOne = 1;
reverseMotorTwo = 1;

arduino_regulated_motorOne is [5, 255, 4, reverseMotorOne];

arduino_regulated_motorTwo is [6, 255, 5, reverseMotorTwo];

when (trigger) {
	if (arduino_analog_sensor_5 >= 165) {
		reverseMotorOne = 0;
		reverseMotorTwo = 0;
		wait 1000;
		reverseMotorOne = 1;
		wait 800;
		reverseMotorTwo = 1;	
	}
	wait 200;
	trigger++;
}
trigger = 1;
