Schematics

WATER SENSOR

This is Argon number one.

LCD Screen

This is Argon number two and how it was setup. (The program used only had a Photon BUT WE USED A PARTICLE ARGON)

LED

This is Argon number three. We used D7 on the Argon as our LED to blink. (The program used only had Photons, BUT WE USED A PARTICLE ARGON)

Code

watelevelsensor

C/C++
int waterSens = A0; //define water sensor
int led = D7;//define led to pin 9
int waterVal; //define the water sensor value



void setup() {
pinMode(led, OUTPUT); //set led as an output
pinMode(waterSens, INPUT);//set water sensor as an input

}

void loop() {


  waterVal = analogRead(waterSens); //read the water sensor
  delay(1000);

String level = String(waterVal);
  Particle.publish("Water_level_value", level, PRIVATE);
  delay(1000);

if (waterVal>0 && waterVal<=300){
    Particle.publish("Water_Level_iot1", "LOW   ",PRIVATE);
    
}
else if (waterVal>300 && waterVal<=600){
    Particle.publish("Water_Level_iot1","MEDIUM",PRIVATE);

}
else if (waterVal>600){
    Particle.publish("Water_Level_iot1", "HIGH  ",PRIVATE );

}

}

lcdscreen

C/C++
// This #include statement was automatically added by the Particle IDE.
#include <LiquidCrystal.h>

LiquidCrystal lcd(5, 4, 3, 2, 1, 0);


void setup() {

    lcd.clear();
    lcd.begin(16, 2);
    lcd.setCursor(0,0);
    lcd.print("Water Level"); //Print line 1: Water Level 
    Particle.subscribe("Water_Level_iot1", Level, "LOW   ");
    Particle.subscribe("Water_Level_iot1", Level, "MEDIUM");
    Particle.subscribe("Water_Level_iot1", Level, "HIGH  ");


}

void loop() {

}

void Level(const char *event, const char *data) {


    lcd.setCursor(0,1);
    lcd.print(data);          //Print line 2: LOW, MEDIUM, or HIGH
}

ledlight

C/C++
int waterVal;
int led = D7;
void setup() {
    
pinMode(led, OUTPUT);

Particle.subscribe("Water_Level_iot1", Level, "LOW    ");


}

void loop() {
    
}

void Level(const char *event, const char *data) {
    
        digitalWrite(led, HIGH);
        delay(1000);
        digitalWrite(led, LOW);
        delay(1000);
        digitalWrite(led, HIGH);

        delay(1000);
        digitalWrite(led, HIGH);
        delay(1000);
        digitalWrite(led, LOW);
        delay(1000);
        digitalWrite(led, HIGH);
        delay(1000);
      

//Blinking: Water level low
//Solid: Water level high
