  1. /*
  2. The Pololu VL53L3CX Time-of-Flight Sensor is a distance sensor that uses STMicroelectronics' VL53L3CX module. To use this sensor with an Arduino, you'll need to install the "Pololu VL53L3CX Arduino Library". Open the Arduino IDE, navigate to "Tools" > "Manage Libraries..." and search for "Pololu VL53L3CX" by Pololu. Install the library and restart the Arduino IDE.
  3.  
  4. Next, connect the Pololu VL53L3CX sensor to your Arduino as follows:
  5.  
  6. Connect the sensor's VIN pin to the Arduino 5V pin.
  7. Connect the sensor's GND pin to the Arduino GND pin.
  8. Connect the sensor's SDA pin to the Arduino A4 pin (or SDA pin if using an Arduino board with dedicated SDA/SCL pins).
  9. Connect the sensor's SCL pin to the Arduino A5 pin (or SCL pin if using an Arduino board with dedicated SDA/SCL pins).
  10. Now, upload the following code to your Arduino:
  11.  
  12. This code initializes the VL53L3CX sensor using the Pololu VL53L3CX Arduino library and starts continuous ranging with a 100 ms inter-measurement period. In the loop(), the sensor's distance reading is obtained using the read() function, and the distance is printed to the serial monitor every second.
  13.  
  14. After uploading the code to your Arduino and opening the serial monitor, you should see the distance readings being printed.
  15.  
  16. You can modify the code to control other devices or make decisions based on the sensor readings according to your project requirements.
