Story

Stay home, stay creative. To swipe away boredom, encourage making, and bring ideas for more quality quarantine days, we made a series of new project tutorials involved with #Arduino, which are all low-cost solutions that respond to the COVID-19 pandemic.

This is the 2nd one: A "Don't Touch Your Face" Hat to keep yourself from unconsciously touching your face so that the virus doesn't enter your eyes, nose, and mouth from your hands.

Please watch the video to find the step-by-step tutorial:

Code

"Don't Touch Your Face" Hat

#include "SR04.h"


#define TRIG_PIN 12
#define ECHO_PIN 11
long a;
SR04 sr04 = SR04(ECHO_PIN, TRIG_PIN);
int buzzer = 10;//the pin of the active


void setup() {
pinMode(buzzer,OUTPUT);//initialize the buzzer pin as an output
}


void loop() {
  a=sr04.Distance();
   if(a<=8&&a>=1)
{
for(int i=0;i<80;i++)
   {
    digitalWrite(buzzer,HIGH);
    delay(1);//wait for 1ms
    digitalWrite(buzzer,LOW);
    delay(1);//wait for 1ms
    }
  }
  digitalWrite(buzzer,LOW);
