AUTOMATIC SOAP DISPENSER USING ARDUINO
BUYING LINK TO AMAZON BELOW :
PROGRAM :
#include <Servo.h>
#include <NewPing.h>
int trigPin = 9;
int echoPin = 10;
int maxDist = 100;
NewPing sonar(trigPin, echoPin, maxDist);
Servo myservo;
int distance;
int pos = 0;
int pos1=0;
void setup()
{
Serial.begin(9600);
myservo.attach(6);
delay(1000);
for (pos = 180; pos >= 0; pos -= 1)
{ // goes from 180 degrees to 0 degrees
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(5); // waits 5ms for the servo to reach the position
}
}
void loop()
{
int distance = sonar.ping_cm();
Serial.print(distance);
Serial.println(" cm");
delay(250);
if(distance>2 && distance<5 )///////////donot give data
{
for (pos = 0; pos <= 180; pos += 1)
{ // goes from 0 degrees to 180 degrees
// in steps of 1 degree
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(5); // waits 5ms for the servo to reach the position
}
for (pos = 180; pos >= 0; pos -= 1)
{ // goes from 180 degrees to 0 degrees
