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… ...

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 ...

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 ...

The additional sensors include a nine-axis Inertial Measurement Unit, as well as temperature, pressure, humidity, light, color, and gestures sensors.
