#include
Servo servo;
int const trigPin = 9;
int const echoPin = 8;
#define red 5
#define green 6
void setup() {
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
pinMode(red,OUTPUT);
pinMode(green,OUTPUT);
servo.attach(10);
}
void loop()
{
int duration, distance;
digitalWrite(trigPin, HIGH);
digitalWrite(trigPin, LOW);// Measure the pulse input in echo pin
duration = pulseIn(echoPin, HIGH);// Distance is half the duration devided by 29.1 (from datasheet)
distance = (duration/2) / 29.1;// if distance less than 0.5 meter and more than 0 (0 or less means over range)
if (distance = 0)
{
servo.write(60);
digitalWrite(green,HIGH);
digitalWrite(red,LOW);
delay(200);
}
else
{
servo.write(10);
digitalWrite(red,HIGH);
digitalWrite(green,LOW);
delay(80);
}
}
