Code Examples

### Example 1: Basic Distance Measurement using Arduino

This example demonstrates how to use the GY-53 VL53L0X sensor module with an Arduino board to measure the distance to an object.
```cpp
#include <Wire.h>
#include <VL53L0X.h>

VL53L0X sensor;

void setup() {
  Wire.begin();
  sensor.init();
  sensor.setTimeout(500);
}

void loop() {
  sensor.startContinuous();
  int distance = sensor.readRangeContinuousMillimeters();
  Serial.print("Distance: ");
  Serial.print(distance);
  Serial.println(" mm");
  delay(50);
}
```
In this example, we include the `Wire` library for I2C communication and the `VL53L0X` library for interacting with the sensor. We initialize the sensor in the `setup()` function and set a timeout value. In the `loop()` function, we start the continuous measurement mode and read the distance using the `readRangeContinuousMillimeters()` function. The distance is then printed to the serial console.

### Example 2: Object Detection using Raspberry Pi (Python)

This example demonstrates how to use the GY-53 VL53L0X sensor module with a Raspberry Pi to detect the presence of an object within a certain distance.
```python
import smbus

bus = smbus.SMBus(1)  # Use I2C bus 1 on Raspberry Pi

def read_distance():
    bus.write_byte(0x29, 0x00)  # Reset sensor
    bus.write_byte(0x29, 0x04)  # Set mode to continuous measurement
    distance = bus.read_word(0x29, 0x85)  # Read distance register
    return distance / 4  # Convert to millimeters

while True:
    distance = read_distance()
    if distance < 500:  # Object detected within 500 mm
        print("Object detected!")
    else:
        print("No object detected.")
    time.sleep(0.1)
```
In this example, we use the `smbus` library to interact with the I2C bus on the Raspberry Pi. We define a function `read_distance()` to read the distance register on the sensor and convert the value to millimeters. In the main loop, we continuously read the distance and check if an object is within a certain range (500 mm in this example). If an object is detected, we print a message to the console.

Note: These examples are for illustration purposes only and may require modification to suit specific use cases and hardware configurations.
