Measure Distance with Laser VL53L0X 6 pin module with LCD1602-I2C for Arduino

This code is to measure distance using laser module ToF Time of Flight VL53L0X 6 pin module. This module is sold on eBay or AliExpress in different color but mostly (as of June 2018) sold in pink color.

In the video you will see how to use this code with LCD1602-I2C or LCD2004-I2c. The distance is selectable as mm or cm.


This is Arduino code to measure distance with VL53L0X and display it on LCD1602 with I2C module
Distance is displayed in mm (melimeter) or cm (centimeter).
