I connected 5 step motors and smps to Arduino in order to give 12v to the step motor,
but it was broken by smoke in Arduino.
Please let me know if you have a solution.
Motor Electrical Specification:
Motor Type: Bipolar Stepper
Step Angle: 1.8 deg.
Holding Torque: 40N.cm (56oz.in)
Rated Current/phase: 1.7A
Phase Resistance: 1.5Ohm±10%
Insulation Resistance: 100MΩ¸ Min, 500VDC
Insulation Strength: 500VAC for one minute
So you see, you have received exactly as much information as you have provided.
You have two options.
Give up and go back to knitting.
Sit down at your keyboard, read the forum instructions, explain how you connected the 12 V power supply ground to the Arduino ground, how you powered the Arduino, what those stepper drivers are (Web-link please) and usable photos of the whole assembly. This is to verify that how you actually connected it matches your proposed schematic.
Unless you are a professional photographer, are equipped and know what you are doing, do not attempt to take photos inside. Take your parts outside in full daylight but not direct sun.
Use a real camera able to focus in detail and if it has no "macro" function, keep at least half a metre away and use the (genuine) zoom.
