As photons (light) land on the detector, the resistance will decrease. The more light is we will have a lower resistance. By reading different values from the sensor, we can detect if is it light , ...

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, ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. Last month we saw [Udo]’s blinkenlight shield that can be used as a lin… ...

Decorative lighting has become quite popular, with options such as LED surface panels, strip lights, COB lights, spotlights, ...

The sensors trigger an Arduino to turn on LEDS on a nearby setup. In the video (which is after the break) you can see the entire thing in action -- which maker Joe says can eventually lead to a ...
