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, ...

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 ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by 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 ...

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