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, ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

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… ...

PHIL is a light tracking robot who is perfectly happy to do it the old-school way. PHIL consists of an Arduino Uno running a twin-servo motion platform, providing the sensor head with pan and tilt ...

The sensors allow devices to automatically adjust the screen brightness based on how light or dark the surroundings are. That, in turn, reduces eye strain and improves power consumption.
