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 ...

This project shows how to build a light gauge that uses an LED bar graph to show the measured brightness level. The function “gauge()” is a good example of using “if” statements to analyze sensor ...

Posts from this topic will be added to your daily email digest and your homepage feed. The long-promised Thread sensor is finally here, but while there are some improvements, Matter’s shortcomings ...

If you’re anything like me you understand the power of Arduino but are stymied by limitations of education, imagination, or wireless connectivity to implement it into your own life. Thanks to the ...

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 ...

Arduino has announced the official release of Arduino IoT Cloud, an “Internet of Things Application Platform” enabling you to easily develop and manage IoT apps. The system first emerged back in ...
