This instructable will show how to control stepper motor taken from DVD-rom
Using Arduino Pro Mini to make pulse to run stepper motor.
What you need is:
1. Stepper motor
2. H-bridge L298N
3. Arduino Pro Mini
Step 1: Stepper Motor
After take motor, soldering cable out at 4 pins of motor. Use your clever hand! It's very small pin.
Step 2: Understand About Stepper Motor
Motor from DVD is kind of bipolar stepper motor
There are 2 coil, called it as A coil and B coil
Pulse implied to coil A and B synchronize will rotate rotor. Detail principle about stepper motor, you can google it.
H-bridge is used to imply pulse to coil A and coil B as pattern on picture (this pattern is taken from another Instructable)
Step 3: Connect Circuit
Connect Arduino to H-bridge, and from H-bridge to motor coil A, coil B
Step 4: Code Works
Code works will imply pulse as pattern on picture
