Скачать или смотреть Smart Street Light System Using LDR and Arduino Project | How to interface LDR sensor to arduino

In this tutorial, I have explained how to build a Smart Street Light System using an LDR (Light Dependent Resistor) and Arduino UNO in Tinkercad Circuits. This project automatically controls the street lights based on ambient light conditions – turning them ON at night and OFF during the day.

✅ Why Watch This Video?

Learn how to interface an LDR sensor with Arduino.

Write simple Arduino code to read LDR values and control LEDs.

Simulate and test the entire project in Tinkercad without hardware.
