Code for Feeder

Arduino
This was coded using Particle's IDE, which is very similar to Arduino's IDE
you will also need to use the Blynk app to set up the email notifications
// This #include statement was automatically added by the Particle IDE.
#define BLYNK_PRINT Serial 
#include <blynk.h>

char auth[] = "<Insert your Blynk authentication pin here>";

Servo myservo;

int pos = 0;
bool foodThere;
bool open;

int led = D1;
int sensorPin = A1;
int value;

int servoLock = 0;

int emailSent = 1;

void setup() {
  pinMode(led, OUTPUT); 
  Serial.begin(9600);
  pinMode(2, OUTPUT);
  myservo.attach(2);
  
  Blynk.begin(auth);
}

void loop() {
    
  value = analogRead(sensorPin);       //Read and save analog value from touch sensor
  value = value/10;
  Serial.println(value);               //Print value
  
  if (value > 100){
    digitalWrite(led, HIGH);
    foodThere = true;
    emailSent=0;
    delay(500);
  }
  else {
    digitalWrite(led, LOW); 
    foodThere = false;
    emailSent = 1;
  }

  delay(500);
  
  if( foodThere == true && servoLock == 0){
    myservo.write(170);
    delay(1000);
    servoLock = 1;
  }
  
  if( foodThere == false && servoLock == 1){
    myservo.write(5);
    delay(5000);
    servoLock = 0;
    myservo.write(170);
    delay(5000);
  }
  
  if( foodThere == false && servoLock == 0 ){
    delay(2000);
    if( foodThere == false && servoLock == 0 && emailSent == 1){
        Blynk.email("Insert Your Email Here", "Food Levels", "Your Conatiner Is Empty!");
       
    }
  }
}
