Code Example
```c
#include <Stepper.h>
// Define stepper motor pins
const int dirPin = 2;
const int stepPin = 3;
// Define stepper motor properties
const int stepsPerRev = 200;
const int motorSpeed = 100;
Stepper stepper(stepsPerRev, dirPin, stepPin);
void setup() {
// Set up stepper motor
stepper.setSpeed(motorSpeed);
}
void loop() {
// Move the stepper motor 100 steps forward
stepper.step(100);
delay(1000);
// Move the stepper motor 100 steps backward
stepper.step(-100);
delay(1000);
}
```
This code example demonstrates how to use the Openbuilds Stainless Steel V Groove Wheel Pulley with Bearing (625ZZ) with a stepper motor to control the movement of a CNC machine or robot. The pulley is attached to the stepper motor shaft, and the V-groove wheel is used to guide the belt or chain that drives the machine.
