This Arduino-powered Shiftbrite LED ambilight setup takes things a step further by automatically adjusting the color and intensity of the ambient lights on the back of the display to match ...

This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

The concept of using an LED as a sensor is much like using a speaker as a microphone. Flip things around, and instead of emitting light, the LED senses it instead. You can see the effect quite ...

which measures the intensity of light bouncing back from an object as an Arduino drives the LED through all possible colors with PWM signals. The sensor needs to be white balanced before use but ...

The Arduino receives this data and can control either a single-color LED or with an RGB LED strip ... to change the colour and intensity of light depending on the weather conditions.If you want to use ...

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 ... light and by detecting its reflection ...
