Cheap Dual Stepper Driver!

Hello everyone!, today i would like to tell you how to make cheap, dual stepper driver!

I hope you enjoy this project for nice robotics project!

Visit my project blog below:

http://do-ityourself-project.blogspot.com/

A stepper motor contains average 4 to make a lot of different direction. It also has 5, 6, even 8 wires!

for this project, we need the 5 wires stepper motor. for another wires(ex: 8) wait for the update!

you also can connect the 6 wires stepper by connecting the common wires as 1 common

Recognize your stepper wires with knowing the common(1 wire usually -) and the coils(4 wires). look the stepper wires colors above!

The most important of this project is make the PCB artwork.

You need the Circuit Wizard software, download below:

For the data, download below:

You also need the components below:

• ULN2003 or ULN 2004

• Connector

that's all that we need!

Connect your stepper wires to your cheap driver!

When you had finished the steps before connect the + and - to your battery, because if you connect your power to arduino it will not enough power!.

and connect your connector(the nail connector) to arduino 1 until 7 pins until it fits in arduino(look the picture).

Copy those code below to your arduino software:

int motorPin1 = 0;

int motorPin2 = 1;

int motorPin3 = 2;

int motorPin4 = 3;

int delayTime = 500;

void setup() {

pinMode(motorPin1, OUTPUT);

pinMode(motorPin2, OUTPUT);

pinMode(motorPin3, OUTPUT);

pinMode(motorPin4, OUTPUT); }

void loop() {

digitalWrite(motorPin1, HIGH);

digitalWrite(motorPin2, LOW);

digitalWrite(motorPin3, LOW);

digitalWrite(motorPin4, LOW);

delay(delayTime);

digitalWrite(motorPin1, LOW);

digitalWrite(motorPin2, HIGH);

digitalWrite(motorPin3, LOW);

digitalWrite(motorPin4, LOW);

delay(delayTime);

digitalWrite(motorPin1, LOW);

digitalWrite(motorPin2, LOW);

digitalWrite(motorPin3, HIGH);

digitalWrite(motorPin4, LOW);

delay(delayTime);

digitalWrite(motorPin1, LOW);

digitalWrite(motorPin2, LOW);

digitalWrite(motorPin3, LOW);

digitalWrite(motorPin4, HIGH);

delay(delayTime); }

If you want to control 2 steppers, add the pins in void setup and edit the code. Maybe you can search in google etc.
