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, ...

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 ...

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 ...

Efficient traffic management in urban areas remains a significant challenge as vehicle density grows and infrastructure ...

An overwhelming majority of handheld devices these days have ambient light sensors built into them. A large percentage of TVs and monitors do, too, and that proportion is growing. The sensors allow ...
