Sample Project:

Materials Required:

• 1 x Arduino UNO/NANO
• 1 x VL53L1X Module
• 1 x I2C LCD Display
• 1 x Breadboard
• Jumper Wires

Connection Overview:

Connect A4 to SDA and A5 to SCL on both the sensor and the LCD display.

Required Library:

• Adafruit_VL53L0X library

Example Code (Serial Output):

#include "Adafruit_VL53L0X.h"
Adafruit_VL53L0X lox = Adafruit_VL53L0X();

void setup() {
  Serial.begin(9600);
  while (!Serial) { delay(1); }
  Serial.println("Adafruit VL53L0X test");

  if (!lox.begin()) {
    Serial.println(F("Failed to boot VL53L0X"));
    while(1);
  }

  Serial.println(F("VL53L0X API Simple Ranging example"));
}

void loop() {
  VL53L0X_RangingMeasurementData_t measure;
  lox.rangingTest(&measure, false);

  if (measure.RangeStatus != 4) {
    Serial.print("Distance (mm): ");
    Serial.println(measure.RangeMilliMeter);
  } else {
    Serial.println("Out of range");
  }

  delay(100);
}

Example Code (I2C LCD Output):

#include "Adafruit_VL53L0X.h"
#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 20, 4);
Adafruit_VL53L0X lox = Adafruit_VL53L0X();

void setup() {
  lcd.init();
  lcd.backlight();
  Serial.begin(9600);
  while (!Serial) { delay(1); }
  Serial.println("Adafruit VL53L0X test");

  if (!lox.begin()) {
    Serial.println(F("Failed to boot VL53L0X"));
    while(1);
  }

  Serial.println(F("VL53L0X API Simple Ranging example"));
}

void loop() {
  VL53L0X_RangingMeasurementData_t measure;
  lox.rangingTest(&measure, false);

  if (measure.RangeStatus != 4) {
    lcd.clear();
    lcd.setCursor(0, 0);
    lcd.print("DISTANCE in mm");
    lcd.setCursor(0, 1);
    lcd.print(measure.RangeMilliMeter);
  } else {
    lcd.clear();
    lcd.setCursor(0, 0);
    lcd.print("DISTANCE in mm");
    lcd.setCursor(0, 1);
    lcd.print("OUT OF RANGE");
  }

  delay(100);
}
