Hello everyone, this is my first project on Arduino Project Hub.
My name is Krishna Srikanth, I am 9 years old. I am a student of MECHATRON ROBOTICS, New Delhi. I have completed a full fledged course on Arduino and electronics in just 2 months. I have always desired to become a scientist in ISRO, Perhaps i’m also taking these small steps at an early age.
In these tough times of COVID-19 Virus, I have made this super easy project Social Distancing Reminder which will help you maintain a distance of 1 metre with another person. This virus spreads rapidly with physical contact and air transmission upto 1 metre. This piezo electric buzzer will create a sound whenever the other person comes as close as 1 metre.
Looking forward to contribute more to this world by more innovative ideas.
Thanks!!
Stay Safe and Happy !

Code Of Project
int pingPin = 9;
int buzzer = 11;
void setup() {
Serial.begin(9600);
pinMode(buzzer, OUTPUT);
}
void loop() {
long duration, cm;
pinMode(pingPin, OUTPUT);
digitalWrite(pingPin, LOW);
delayMicroseconds(2);
digitalWrite(pingPin, HIGH);
delayMicroseconds(5);
digitalWrite(pingPin, LOW);
pinMode(pingPin, INPUT);
duration = pulseIn(pingPin, HIGH);
cm = microsecondsToCentimeters(duration);
Serial.print("Distance: ");
Serial.print(cm);
Serial.print("cm");
Serial.println();
if(cm < 100) {
digitalWrite(buzzer, HIGH);
}
else {
digitalWrite(buzzer, LOW);
}
delay(100);
}
long microsecondsToCentimeters(long microseconds) {
return microseconds / 29 / 2;
}
