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… ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

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 ...

While searching for affordable UV light sensors, I came across a bunch of cheap little modules of what appear to be a great UV light sensor for Arduino projects. If you go online and look you can see ...

With over 20 unique sensor types, and the ability to be used with several different development platforms, Tarts wireless sensors allow for endless sensing, monitoring and control possibilities.

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.
