As we are living in a pandemic, developing products with a touchless function will undoubtedly assist to limit contact.
As we are living in a pandemic, developing products with a touchless function will undoubtedly assist to limit contact, as people are concerned about viruses and germs spreading through things we touch on a daily basis.
Ameba RTL8722DM is a low-power dual-band WLAN and Bluetooth Low Energy SoC by Realtek. The RTL8722DM also include memory for Wi-Fi protocol functions and application making it simple for anyone to develop various kind of IoT applications. At the same time it has a wide range of peripheral interfaces. With all these interfaces, it can connect to most of the electronics components like LEDs, temperature and humidity sensors, and so on.

Firstly connect up the Servo Motor, Ultrasonic sensor with the AmebaD board.
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);
}
}

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.
