Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

This Arduino-based project simulates a Formula 1 race start light system and measures the user's reaction time using an ultrasonic sensor. Instead of pressing a button, the user waves a hand to start, ...

This project demonstrates an interrupt-based embedded system built using the Arduino Nano 33 IoT, a BH1750 light sensor, and a slide switch. The built-in LED is controlled through external ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

Ambient lighting systems provide accent and subtlety to homes, and are also a favorite of designers of luxury products wishing to highlight their wares. Apple stores, for example, use white light with ...

Walking safely and confidently can be a challenging task for visually impaired individuals, but with the help of technology, we can make it easier for them. This DIY Blind Stick is an innovative yet ...

The [Libelium] team wanted to help people in Japan measure radiation in their surroundings following the nuclear accident in Fukushima. Because of the affordability and seeming ubiquity of the Arduino ...
