This document outlines instructions for programming a light-dependent resistor (LDR) sensor using a Wemos D1 R32 microcontroller board. It includes sections on the materials needed, calibration of light measurements, exercises for measuring light levels and printing calibrated light values in lux, and checking if conditions are too light or dark. The document is authored by Leopoldo Armesto, a senior lecturer at Universitat Politècnica de València.
