Code

Led Argon

C/C++
This code is what is running on the argon that controls the lights
int red = A2;
int green = A3;
int blue = A1;
int color[3] = {255, 255, 255};

int thirtySeconds = 0;
int i = 0;
bool start = false;
bool active = false;
int hour = 5;
int minute = 45;

int hallSensor = D7;

int chooseColor(String cmd);
int chooseTime(String cmd);
int on(String cmd);
int off(String cmd);
int doorOpen(String cmd);

void setup() {
    pinMode(red, OUTPUT);
    pinMode(green, OUTPUT);
    pinMode(blue, OUTPUT);
    
    Particle.function("chooseColor", chooseColor);
    Particle.function("chooseTime", chooseTime);
    Particle.function("on", on);
    Particle.function("off", off);
    Particle.function("doorOpen", doorOpen);
    
    Time.zone(-6);
}

void loop() {
    int now = Time.now();
    
    if (Time.hour() == hour && Time.minute() == minute && !start){
        start = true;
        thirtySeconds = now + 30;
    }
    if (start){
        if (now == thirtySeconds){
            i++;
            thirtySeconds += 30;
            analogWrite(red, i/30 * color[0]);
            analogWrite(green, i/30 * color[1]);

        }
        if (Time.minute() == 30){
            start = false;
        }
    }
}

int chooseColor(String cmd){
    if (!(sscanf(cmd, "%d,%d,%d", &color[0], &color[1], &color[2]) == 3)){
        color[0] = 255;
        color[1] = 255;
        color[2] = 255;
        return 0;
    }

        on("");
    }

    if (!sscanf(cmd, "%d:%d", &hour, &minute) == 2){
        hour = 5;
        minute = 45;
        return -1;
    }
    return 0;
}

int on(String cmd){
    start = false; 
    
    if (!(cmd == "")){
        sscanf(cmd, "%d,%d,%d", &color[0], &color[1], &color[2]);
    }
    
    analogWrite(red, color[0]);
    analogWrite(green, color[1]);

    }
    if(active){
        delay(2000);

Hall Sensor Argon

C/C++
This is the code running on the argon by the door
int hall = 7;
int led = 6;

bool state = false;
int pastState = LOW;


void setup() {
    pinMode(hall, INPUT);
    pinMode(led, OUTPUT);
}

void loop() {
    int hallS = digitalRead(hall);

    //magnet close to sensor
    if (hallS == HIGH && pastState != HIGH){
        Particle.publish("doorClose");
    }
    
    //magnet pulled away
    if (hallS == LOW && pastState != LOW){
        Particle.publish("doorOpen");
    }
    
    pastState = digitalRead(hall);
    delay(100);

}
