Buenas, estoy realizando con mis compañeros de instituto un radar que detecta obstrucciones con un servomotor y un sensor ultrasónico (HC-SR04) conectado a un arduino 2560 y quisimos controlar su activación y apagado con un pulsador.
Estuvimos buscando tutoriales y recopilando códigos por internet y logramos casi todo, excepto que una vez el servomotor está funcionando no deja de funcionar cuando vuelvo a apretar el pulsador, como si no saliera del loop, adjunto la codificación debajo. Gracias.
// Includes the Servo library
#include <Servo.h>.
int buttonState=0;
boolean state;
// DEFINIMOS TODOS LOS PINES, PULSADOR, TRIG Y ECO
int pulsador=9;
const int trigPin = 10;
const int echoPin = 11;
// Variables for the duration and the distance
long duration;
int distance;
Servo myServo; // Creates a servo object for controlling the servo motor
void setup() {
pinMode(pulsador, INPUT);
pinMode(trigPin, OUTPUT); // Sets the trigPin as an Output
pinMode(echoPin, INPUT); // Sets the echoPin as an Input
Serial.begin(9600);
myServo.attach(12); // PIN DEL SERVOMOTOR
}
void loop() {
buttonState=digitalRead(pulsador);
if (buttonState==HIGH){
if(state==false){
state=!state;
delay(250);
}
else{
state=false;
delay(250);
}
}
if(state==true){
for(int i=0;i<=180;i++){
myServo.write(i);
delay(40);
distance = calculateDistance();// Calls a function for calculating the distance measured by the Ultrasonic sensor for each degree
Serial.print(i); // Sends the current degree into the Serial Port
Serial.print(","); // Sends addition character right next to the previous value needed later in the Processing IDE for indexing
Serial.print(distance); // Sends the distance value into the Serial Port
Serial.print("."); // Sends addition character right next to the previous value needed later in the Processing IDE for indexing
}
// Repeats the previous lines from 180 to 0 degrees
for(int i=180;i>0;i--){
myServo.write(i);
delay(40);
distance = calculateDistance();
Serial.print(i);
Serial.print(",");
Serial.print(distance);
Serial.print(".");
}
}
}
// Function for calculating the distance measured by the Ultrasonic sensor
int calculateDistance(){
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
// Sets the trigPin on HIGH state for 10 micro seconds
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH); // Reads the echoPin, returns the sound wave travel time in microseconds
distance= duration*0.034/2;
return distance;
