In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

Abstract: The growing need of energy efficiency and the sustainability of urban infrastructure has resulted in the use of smart technologies to automate the usage of public utilities. An example of ...

This project demonstrates an environment-aware smart LED control system using Arduino. A potentiometer is used to simulate ambient light levels, while an ultrasonic sensor detects the distance of ...

Abstract: This study describes the optimization of solar cell electrical power with variations in slope angles using timer-based panel drive (DS3231 RTC) and light sensor (LDR). There are three solar ...

Driving at night often causes discomfort and accidents due to improper usage of high-beam headlights. This project aims to automatically dim headlights when oncoming vehicles are detected, improving ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...
