Circuit Setup

1. Connect the VL53L0X sensor to the Arduino using I2C (SDA, SCL, VCC, and GND).

The VL53L0X uses laser light to accurately measure the distance to an object, which is then sent to the Arduino for processing.

Code for Proximity Sensing

Upload the following code to your Arduino to measure the distance using the VL53L0X sensor:

#include 
#include 

VL53L0X sensor;

void setup() {
  Serial.begin(9600);
  Wire.begin();
  sensor.init();
  sensor.setTimeout(500);
}

void loop() {
  Serial.print("Distance: ");
  Serial.print(sensor.readRangeSingleMillimeters());
  Serial.println(" mm");
  delay(1000);
}
            

Explanation

The VL53L0X sensor measures the time it takes for a laser pulse to reflect off an object, calculating the distance. The value is sent back to the Arduino.

Troubleshooting

• If no data is being read, check the sensor’s wiring and I2C connections.
• Ensure the sensor has a clear line of sight to the object being measured.
