Code Examples

### Example 1: Arduino Linear Actuator Control

In this example, we'll demonstrate how to use the SC8UU Linear Bearing with an Arduino board to control a linear actuator. We'll use the bearing as a guide for the actuator's moving rod.

```c++
const int stepPin = 2;  // Define the step pin for the stepper motor
const int dirPin = 3;  // Define the direction pin for the stepper motor

void setup() {
  pinMode(stepPin, OUTPUT);
  pinMode(dirPin, OUTPUT);
}

void loop() {
  // Move the actuator forward
  digitalWrite(dirPin, HIGH);
  for (int i = 0; i < 100; i++) {
    digitalWrite(stepPin, HIGH);
    delayMicroseconds(500);
    digitalWrite(stepPin, LOW);
    delayMicroseconds(500);
  }

// Move the actuator backward
  digitalWrite(dirPin, LOW);
  for (int i = 0; i < 100; i++) {
    digitalWrite(stepPin, HIGH);
    delayMicroseconds(500);
    digitalWrite(stepPin, LOW);
    delayMicroseconds(500);
  }
}
```

In this example, we're using the SC8UU Linear Bearing to guide the moving rod of the linear actuator. The Arduino board controls the stepper motor, moving the rod back and forth along the bearing.

### Example 2: Raspberry Pi Robotics Project

In this example, we'll demonstrate how to use the SC8UU Linear Bearing in a robotics project using a Raspberry Pi and Python.

```python
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)

# Define the motor pins
motor_forward = 17
motor_backward = 23

GPIO.setup(motor_forward, GPIO.OUT)
GPIO.setup(motor_backward, GPIO.OUT)

def move_forward():
  GPIO.output(motor_forward, GPIO.HIGH)
  GPIO.output(motor_backward, GPIO.LOW)
  time.sleep(1)

def move_backward():
  GPIO.output(motor_forward, GPIO.LOW)
  GPIO.output(motor_backward, GPIO.HIGH)
  time.sleep(1)

while True:
  move_forward()
  move_backward()
```

In this example, we're using the SC8UU Linear Bearing as part of a robotic system controlled by a Raspberry Pi. The Python script controls the motor, moving the robot's arm or mechanism back and forth along the bearing.

These examples demonstrate the versatility of the SC8UU Linear Bearing in various IoT applications, from robotics to automation and precision engineering. By providing smooth and accurate linear movement, this bearing enables developers to create complex systems with ease.
