![]() But what the wiring should be? If it had 5 wires I would have done it like this schematics. Here, we are using six wire unipolar stepper motor. Since I do not have a driver at hand, I need to convert the circuit so it works with 4 transistors instead. Rotating stepper motor in clockwise and counter clockwise directions alternately. And this is exactly the source of confusion: On arduino website, the sample circuit's stepper has 4 wires and is directly connected to a driver IC (a LMxxx), and the driver is connected to Arduino. ![]() I use the MOSFETs as fast switches: 4 Arduino pins control 4 MOSFET transistors. But a 4-wire doesn't make sense! there must be 2 or 4 poles in a motor, and each pole needs a connection to common ground, so there must be 5 wires, how does a 4 wire work? I'm using MOSFET for driving the stepper, not LMxxxīecause I forgot to buy one, and I can't get my hands on one for a couple of days. The two sketches can be combined into one, storing the numbers into EEPROM. We can write down these numbers to later enter them into the Turntable sketch. The serial interface shows the number of steps to the current position. All the pictures and circuits of easy tutorials I found on Google had 5 wires, (and those with 4 wires had different color coding anyway). For the tuning we will use two push buttons, one to rotate CW, one to rotate CCW. A two-wire control program is shown for the Wiring/Arduino Stepper. ![]() Wires are colored: white, blue, red, yellow. The unipolar stepper motor has five or six wires and four coils (actually two coils. Is it okay if my stepper motor has exactly 4 wires? ![]() Today I bought a stepper motor to play with, after 12 hours of struggling with it, I haven't been able to figure out how to connect it to an Arduino. Simulate this circuit – Schematic created using CircuitLab This tutorial provides the Arduino codes for two cases: One stepper motor + one limit switch, One stepper motor + two limit switches. ![]()
