Photoresistor Argon (Argon2)

C/C++
This code is used for Argon2 which only has the photoresistor connected to it

Water Sensor Argon (Argon1)

C/C++
This code is used for the Argon with only the water sensor connected to it (Argon1)
int waterVal; //define variable

int LEDwaterP=D2;
int LEDlightP=D3;

int waterPercent;

pinMode(LEDwaterP,OUTPUT);
pinMode(LEDlightP,OUTPUT);

Particle.variable("Water Value",&waterVal,INT);

Serial.begin(230400);//begin serial monitor for checking values via the serial monitor

Particle.subscribe("Light Event", lightsCheck, MY_DEVICES);
Particle.subscribe("BeWater", waterCheck, MY_DEVICES);

}
