This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

// Tested with green LED an 1 kOhm resistor at pin A5. // LED produce up to 1.4 voltage and 3 micro amps current at light. // The current is very small and messurements don not provide stable results.

Abstract: Drunk driving remains a significant issue worldwide, with thousands of lives lost every year due to accidents caused by individuals operating vehicles under the influence of alcohol. The ...

Abstract: In this work an integrated filter-less BiCMOS based color sensor is presented. It is capable of determining the center wavelength of a monochromatic light source in the visible range. This ...

Think about how easily you recognize a friend in a dimly lit room. Your eyes capture light, while your brain filters out background noise, retrieves stored visual information, and processes the image ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...
