Hello, I do the same hardware connection and programming but my servo motor doesn’t rotate but show my ultrasonic sensor value…
Here is the link to the same project.
What is the problem I couldn’t figure out
Note: 1. I have written the same code and the hardware connection is the same.
2. My motor works fine
The problem I am facing which I GUESS is
- Arduino Code (library Problem)
- Hardware Connection among arduino and Bolt WiFi Module
- what is bolt cloud pro(Do I required it)
Here is the Arduino code
// Includes the Servo library
#include <Servo.h>
#include <SoftwareSerial.h>
SoftwareSerial mySerial(0,1);
// Defines Tirg and Echo pins of the Ultrasonic Sensor
const int trigPin = 9;
const int echoPin = 10;
// 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(trigPin, OUTPUT); // Sets the trigPin as an Output
pinMode(echoPin, INPUT); // Sets the echoPin as an Input
Serial.begin(9600);
myServo.attach(11); // Defines on which pin is the servo motor attached
}
void loop() {
// rotates the servo motor from 15 to 165 degrees
for(int i=15;i<=165;i++){
myServo.write(i);
delay(30);
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 165 to 15 degrees
for(int i=165;i>15;i–){
myServo.write(i);
delay(30);
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;
}
here is the hardware connection pic
I hope I get the doubts clear as soon as possible
