Week 9 - Arduino Coding Upload and Blynk Setting (Troubleshooting Week)

Belowis the coding use in arduino for the sorting and monitoring purposes:

#include <Servo.h>

Servo myservo1;  // create servo object to control a servo


#define BLYNK_PRINT Serial
#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>

char auth[] = "rPCNUbMxbzdkCQ5ERfCUj-83Jj5eGouh";
char ssid[] = "Wifi_Project";
char pass[] = "1a2b3c4d5e";
#define ESP8266_BAUD 115200
ESP8266 wifi(&Serial);

#define trigPin1 2
#define echoPin1 3

#define trigPin2 4
#define echoPin2 5

int ir,metal;

long duration, distance, Sensor1,Sensor2;

void setup() {

   myservo1.attach(9);
      myservo1.write(90);
pinMode(trigPin1, OUTPUT);
pinMode(echoPin1, INPUT);
pinMode(trigPin2, OUTPUT);
pinMode(echoPin2, INPUT);
pinMode(A0,INPUT);
 Serial.begin(ESP8266_BAUD);
 //Serial.begin(9600);
 delay(10);
 Blynk.begin(auth, wifi, ssid, pass);

}

void loop() {
 Blynk.run();

ir = digitalRead(A0);
metal=digitalRead(A1);

SonarSensor(trigPin1, echoPin1);
Sensor1 = distance;
Serial.print("Sensor Metal: ");
Serial.println(Sensor1);

SonarSensor(trigPin2, echoPin2);
Sensor2 = distance;
Serial.print("Sensor Non Metal: ");
Serial.println(Sensor2);

Serial.print("IR: ");
Serial.println(ir);

Serial.print("Metal: ");
Serial.println(metal);

Blynk.virtualWrite(0,Sensor1);
Blynk.virtualWrite(1,Sensor2);

if(metal == 0 && ir == 1) //no object
{
    myservo1.write(90);
}

if(metal == 1 && ir == 0) //metal
{
    myservo1.write(50);
}

if(metal == 0 && ir == 0) //non metal
{
    myservo1.write(130);
}

delay(1000);

}

void SonarSensor(int trigPin,int echoPin)
{
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = (duration/2) / 29.1;

}

The project is success even though the servo motor is a bit loose and needed to be glue.

Lastly is the blynk apps display, the project will not move if not linked to the apps/wifi.
