Tempat Sampah Pintar Berbasis Arduino

kali ini bagaimana cara membuat tempat sampah berbasis arduino. adapun yang perlu di persiapkan diantara lain adalah :

Arduino Uno
Ultrasonic Sensor
Servo

Kode program arduino


#include    //servo library
Servo servo;     
int trigPin = 5;    
int echoPin = 6;   
int servoPin = 7;
int led= 10;
long duration, dist, average;   
long aver[3];   //array for average


void setup() {       
    Serial.begin(9600);
    servo.attach(servoPin);  
    pinMode(trigPin, OUTPUT);  
    pinMode(echoPin, INPUT);  
    servo.write(0);         //close cap on power on
    delay(100);
    servo.detach(); 
} 

void measure() {  
 digitalWrite(10,HIGH);
digitalWrite(trigPin, LOW);
delayMicroseconds(5);
digitalWrite(trigPin, HIGH);
delayMicroseconds(15);
digitalWrite(trigPin, LOW);
pinMode(echoPin, INPUT);
duration = pulseIn(echoPin, HIGH);
dist = (duration/2) / 29.1;    //obtain distance
}
void loop() { 
  for (int i=0;i<=2;i++) {   //average distance
    measure();               
   aver[i]=dist;            
    delay(10);              //delay between measurements
  }
 dist=(aver[0]+aver[1]+aver[2])/3;    

if ( dist<50 ) {
//Change distance as per your need
 servo.attach(servoPin);
  delay(1);
 servo.write(0);  
 delay(3000);       
 servo.write(150);    
 delay(1000);
 servo.detach();      
}
Serial.print(dist);
}

noted : perlu di ingat jika pada saat melakukan upload code arduino mengalami error pastikan sudah install beberapa library yang di butuhkan pada software arduino.

cara nya cukup mudah cara instal pilih menu klik menu bar skecth > include library > manage library kemudian search library yg di butuhkan setelah sudah ketemu baru klik install. done. nah terakhir kalian bisa klik ulang pada upload arduino selesai.
