Using pulsed light enables the sensor to distinguish the reflection from the ambient infrared environment. However, do not put it too close to a strong source of infrared radiation because if the ...

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 ...

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 ...

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