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 ...

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 ...

How fast does your heart beat? It’s a tough question to answer, because our heart rate changes all the time depending on what we’re doing and how our body is behaving. However, ...

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

Diaz Merced’s collaborators equipped an Arduino with a light-detecting sensor and speaker, and programmed it to convert light into a clicking noise.

Built your very own parking sensors for the car using nothing more than an Arduino board and cheap components you can find online ...

Ambient light sensors can reveal your device activity. How big a threat is it? For now, there's no reason for concern, but that could change in coming years.
