Code Examples

### Example 1: Using the MR105ZZ in a Robotics Project with Arduino

In this example, we will use the MR105ZZ bearing in a robotics project to create a precision wheel assembly for a small robot.

```c++
const int motorPin = 9;  // Pin for motor control signal
const int sensorPin = A0;  // Pin for sensor input

void setup() {
  pinMode(motorPin, OUTPUT);
  pinMode(sensorPin, INPUT);
}

void loop() {
  int sensorValue = analogRead(sensorPin);
  int motorSpeed = map(sensorValue, 0, 1023, 0, 255);
  analogWrite(motorPin, motorSpeed);
  
  // Use the MR105ZZ bearing to support the wheel assembly
  // Connect the wheel to the motor shaft, which passes through the bearing
  // The bearing reduces friction and allows for smooth wheel rotation
}
```

### Example 2: Using the MR105ZZ in a Drone UAV with ESP32

In this example, we will use the MR105ZZ bearing in a drone UAV project to create a precision gearbox for the propellers.

```c++
#include <WiFi.h>
#include <esp_wifi.h>

const int motorPin = 18;  // Pin for motor control signal
const int gearRatio = 3;  // Gear ratio for propeller speed

void setup() {
  WiFi.begin("UAVNetwork", "dronepassword");
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }

Serial.println("Connected to WiFi");
  Serial.println("Initializing motor...");
  pinMode(motorPin, OUTPUT);
}

void loop() {
  int propellerSpeed = map(analogRead(A0), 0, 1023, 0, 255);
  analogWrite(motorPin, propellerSpeed);
  
  // Use the MR105ZZ bearing to support the gearbox assembly
  // Connect the propeller to the motor shaft, which passes through the bearing
  // The bearing reduces friction and allows for smooth propeller rotation
  delay(20);
}
```
