You did a very impressive work here and thank you for

sharing it generously.

I just disassembled my epson printer took this specific

em546 motor and googled for info, and got interested in

your blog. I need the exact thing you did but im new to

arduino (read alot about it in the past but never owned it

yet). It surprised me that your from manila! kabayan! i

wish to contact you and inquire some questions if it wont

be of burden to you..

is it possible that this motor (together with the gear with

metal bushing beside it in the printer) could hold or rotate

if i attach a camera on it? to be used in panning.

is it possible to add speed control to your code/circuit?

thanks and God bless your generosity.

Hello now i have EM 546 but i don’t know spec it. U can

tell me?

My code

#include

const int STEPS = 200;

Stepper stepper_F(STEPS, 11, 10, 9, 8);

void setup(){

Serial.begin(9600);

}

void loop(){

int i=0;

if (Serial.available() > 0){

int motoraction = Serial.read();

switch (motoraction){

case ‘a’:

Serial.println(“clockwise”);

stepper_F.setSpeed(140);

for(i=0;i<30;i++)

{

stepper_F.step(STEPS);

}

(10)

}

delay(500);

break;

//move counterclockwise

case 'b':

stepper_F.setSpeed(5);

stepper_F.step(-STEPS);

delay(500);

break;

}

- it slow and have a noise sound.
