Hello to all the Arduino community!
I am totally new to the Arduino world, and I find it absolutely amazing! (I am a total newbie in electronics for now but would like to learn more about it!)
I just recently started a small Arduino project whose goal is to simply drive a stepper motor : Stepper Motor: Bipolar, 200 Steps/Rev, 35×36mm, 2.7V, 1 A/Phase (https://www.pololu.com/product/1209) using a L293D motor controller, and a remote power supply source (http://fr.rs-online.com/web/p/alimentations-enfichables/7066524/) for the motor.
Here is a small scheme of the setup :
The code that I am using to drive the motor was borrowed from a tutorial that I found on the net :
#include <Stepper.h>
const int stepsPerRevolution = 512; // change this to fit the number of steps per revolution
// for your motor
// initialize the stepper library on pins 8 through 11:
Stepper myStepper(stepsPerRevolution, 8,9,10,11);
void setup() {
// set the speed at 60 rpm:
myStepper.setSpeed(10);
// initialize the serial port:
Serial.begin(9600);
}
void loop() {
// step one revolution in one direction:
Serial.println("clockwise");
myStepper.step(stepsPerRevolution);
delay(500);
// step one revolution in the other direction:
Serial.println("counterclockwise");
myStepper.step(-stepsPerRevolution);
delay(500);
}
The issue I have is that when I load the code to the Arduino, plug the power supply, I can only see a slight movement of the rotor back and forth, but no complete rotation movement... I guess that it's a power issue? I am using a 24V, 1A power supply.
But since I'm only a beginner in the field I can't really figure out the problem... Would you mind helping me out?
