This project demonstrates how to interface an LDR (Light Dependent Resistor) with the Arduino UNO R4 WiFi to measure light intensity levels. The LDR is connected in a voltage divider configuration: ...

A minimal project that reads an LDR on analog pin A0, maps the 0\–1023 ADC value to 0\–100% and prints both the raw value and percentage to the serial monitor at 9600 baud.
