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 ...

Because his blinkenlight shield can be used as a light sensor, all that’s needed is a mirror and a pretty long line of sight. There’s a few problems with the setup though: with the Arduino ...

the BH1600FVC and BH1710FVC from Rohm allow LCD-based systems to adjust brightness based on ambient light. A pair of ambient light sensors from Rohm Co. Ltd. are compatible with any light source ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close ... receiver IR1 is only ...
