Introduction: 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:
Step 1: Recognizing Your Stepper Motor!
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!
Step 2: Make the PCB!
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!
Step 3: Connecting Your Stepper Wires!
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).
Step 4: Arduino Code and Test Your Stepper Motor!
Copy those code below to your arduino software:
/* Stepper Copal

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); }
Step 5: Finishing
If you want to control 2 steppers, add the pins in void setup and edit the code. Maybe you can search in google etc.
