My Arduino gets stuck some times.

[shalinipandurangan]

I am new to Arduino programming. I have a Arduino micro and I have connected it to two IR sensors and three servo's. It get's stuck sometimes. I have a 12v power supply (In order to avoid my Arduino from burning out I am using a step down voltage regulator) let me know if this is necessary. I am attaching the code. I am not sure if it's the power issue or something else. could some one please let me know how to fix this issue. I also intend to add one temperature sensor and fan to this connection.

CODE:

#include <Servo.h>

Servo myservo; // create servo object to control a servo
Servo myservo1;
Servo myservo2;
Servo myservo3;
Servo myservo4;
int val = 10;

void setup() {
Serial.begin(9600);
pinMode(2, INPUT);// set pin as input
pinMode(10, INPUT);
myservo.attach(5);
myservo1.attach(8);
myservo2.attach(4);
myservo.write(25);
}

void loop() {
//Written for Robojax on Dec 28, 2017
int detect = digitalRead(2);// read obstacle status and store it into "detect"
int detect1 = digitalRead(10);
if (detect == LOW) {
Serial.println("Obastacle on the way");
myservo.write(90);
delay(2000);
myservo.write(20);
delay(500);
myservo1.write(150);
myservo2.write(150);
delay(300);
}

else {

Serial.println("All clear");
if (detect1 == LOW) {
myservo1.write(20);
myservo2.write(20);
delay(1000);
myservo.write(90);
delay(1000);
myservo.write(20);
}
}
delay(300);
}

More information please. What "step-down voltage regulator"? What servos? How is everything connected? A schematic/circuit diagram is needed. What does "gets stuck" mean? Describe what actually happens.

I guess it's probably a power problem. Maybe you are trying to power the servos from the Arduino or connect them through a breadboard or your regulator can't provide enough current or....

I havent used servos, so I'm just asking this as a question; does the servo library play nicely with delay()?

Yes it does. So that's not the problem. But since we haven't heard back from the OP we may never know what was.

Hi,
Welcome to the forum.

Please read the post at the start of any forum , entitled "How to use this Forum".
OR
http://forum.arduino.cc/index.php/topic,148850.0.html.
Then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

Thanks.. Tom...

Connect your servo's red wire to the step down regulator and feed the Arduino from a separate step down regulator. Servo's create a lot of power fluctuations that may "hang" your Arduino.
