All,
I am new to this in addition new to programming. I am trying to dive a small motor by using a ultrasonic trigger. I set up an arduino driving a small servo but am not sure how to drive a motor instead turning it on for a few seconds then off when triggered. Any help is appreciated
I used the attached code to make it work.
servo.txt (797 Bytes)
#include <Servo.h>
#define trigPin 7
#define echoPin 6
Servo servo;
void setup()
{
Serial.begin (9600);
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
servo.attach(8);
}
void loop()
{
long duration, distance;
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = (duration/2) / 29.1;
if (distance < 5)
{
Serial.println("the distance is less than 5");
servo.write(120);
}
else
{
servo.write(0);
}
if (distance > 60 || distance <= 0)
{
Serial.println("The distance is more than 60");
}
else
{
Serial.print(distance);
Serial.println(" cm");
}
delay(500);
}
