  Programming

  #include <AmebaServo.h>
  
  AmebaServo myservo;
  const int trigger_pin = 12;
  const int echo_pin = 13;
  const int inter_time = 100;
  int time = 0;
  
  void setup() 
  {
    Serial.begin(115200);
    myservo.attach(8,500,2400);
    pinMode(trigger_pin, OUTPUT);
    pinMode(echo_pin,INPUT);
    delay(3000);
  }
  
  void loop() 
  {
    float duration,distance;
    digitalWrite(trigger_pin,HIGH);
    delayMicroseconds(1000);
    digitalWrite(trigger_pin, LOW);
    duration = pulseIn(echo_pin,HIGH);
    distance = (duration/58);
    Serial.print(distance);
    Serial.println(" cm");
    time = time + inter_time;
    delay(inter_time);
    if(distance < 10)
    {
      for(int i = 1500; i>= 1100; i-=25)
      {
        myservo.writeMicroseconds(i);
        Serial.println("2");
        delay(1000);
      }
      delay(1000);
      for(int i=1100; i<=1500; i+=25)
      {
        myservo.writeMicroseconds(i);
        Serial.println("1");
        delay(1000);
      }
      }
    }

  Final Results

  When you place your hand near the ultrasonic sensor, the dustbin will open and when your hand is away from it, the dustbin would close.
