Most ambient lights and sensors are designed to generate light to even out the picture on the front of the panel and reduce any light bleed from the back of an LCD display. This Arduino-powered ...

Researchers at the University of Washington's aptly named Ubiquitous Computing Lab can turn any LCD monitor in your hous into a touchscreen, with nothing more than a $5 sensor that plugs into the ...

With spectral sensitivity similar to characteristics of the human eye, the BH1600FVC and BH1710FVC from Rohm allow LCD-based systems to adjust brightness based on ambient light.

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 ...

As photons (light) land on the detector, the resistance will decrease. The more light is we will have a lower resistance. By reading different values from the sensor, we can detect if is it light , ...

The sensor can also supply flicker measurements to the mobile phone’s applications processor to support flicker cancellation firmware at frequencies other than 50/60Hz by using the internal FIFO ...

The 4-inch optical sensor LCD pad in this notebook PC is more than just a conventional track pad thanks to its new touch-sensing recognition method: in addition to conventional mouse operation, it ...
