Schematics

Schematic for Trash Headquarters

This is the schematic for the Trash Headquarters that flashes if a Trashcan is full.

Schematics for Trash Sensor Setup

This is the schematic for creating the sensor that looks into the trash can

Code

Trash Can Sensor Code 1

Arduino
This is the code used for the sensors that detect the trash level of the first trash can
// This #include statement was automatically added by the Particle IDE.
#include <HC_SR04.h> //Used to set up the library for the ultrasonic sensor

double cm = 0.0;
bool beam_status = false;

int trigPin = D4; //Setting up the pin that sends out signals on the Ultrasonic sensor
int echoPin = D5; //Setting up the pin that receives out signals on the Ultrasonic sensor
int ledPin = D7; //Setting up the pin for the LED indication
int buzzPin = D2; //Setting up the signal pin for the buzzer


HC_SR04 rangefinder = HC_SR04(trigPin, echoPin); //Enabling the ultrasonic sensor

void setup() 
{
    Spark.variable("cm", &cm, DOUBLE);
    pinMode(ledPin,OUTPUT);
    pinMode(buzzPin,OUTPUT);
    Particle.subscribe("warningRyanTrash", myHandler); //Subscribes to the event being published by the headquarters
}

void loop() 
{
    cm = rangefinder.getDistanceCM(); //This is initializing the sensor to look for distances in cm
    if (cm<15){
        if (beam_status==false){
            Particle.publish("trashLevelRyan", "too_high"); //If something is closer than 15 cm of the sensor, the Argon will publish this event to the cloud once
            beam_status = true;   
        }
    } else {

            beam_status = false;
        }
    }
    delay(500);
}

{    
    digitalWrite(ledPin,HIGH);
     if (strcmp(data,"full")==0) {      //If the event "warningNimitTrash" being published from the headquarters says "full", this loop is excuted
        digitalWrite(ledPin,HIGH);      //Turn on LED
        analogWrite(buzzPin,130);       //Turn on buzzer
    }
    else if (strcmp(data,"clean")==0) { //If the event "warningNimitTrash" being published from the headquarters says "clean", this loop is excuted
        digitalWrite(ledPin,LOW);       //Turn off LED

Headquarters Code

Arduino
This is the code used for creating the trash hub - the device that will sense the trash levels and create a response based on that.
int led_pin1 = D7; //Sets up the pin first LED (on board the Argon)
int led_pin2 = A0; //Sets up the pin for second LED


void setup() {
  pinMode(led_pin1,OUTPUT); 
  pinMode(led_pin2,OUTPUT);
  Particle.subscribe("trashLevelNimit", myHandler1); //Subscribes to the sensor detecting the trash in first location
  Particle.subscribe("trashLevelRyan", myHandler2); //Subscribes to the sensor detecting the trash in second location
}


void loop() {

}


void myHandler1(const char *event, const char *data)
{
    if (strcmp(data,"too_high")==0) { //Compares incoming data from the event "trashLevelNimit" to the characters "too_high". If they match, then it excutes this loop
        digitalWrite(led_pin1,HIGH); //Turns on LED
        Particle.publish("warningNimitTrash","full"); //Publishes an event that that says "full" which is recieved by the trash can sensor subscribed to it
    }
    else if (strcmp(data,"all_clear")==0) { //Compares incoming data from the event "trashLevelNimit" to the characters "all_clear". If they match, then it excutes this loop
        digitalWrite(led_pin1,LOW); //Turns off LED
        Particle.publish("warningNimitTrash","clean"); //Publishes an event that that says "clean" which is recieved by the trash can sensor subscribed to it
    }
}

void myHandler2(const char *event, const char *data)
{
    if (strcmp(data,"too_high")==0) { //Compares incoming data from the event "trashLevelNimit" to the characters "too_high". If they match, then it excutes this loop
        digitalWrite(led_pin2,HIGH); //Turns on LED
