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 ...

Light Sensing: The system uses a light sensor to detect the intensity of ambient light. Automatic Lighting: Based on the sensor readings, the system can turn lights on or off to maintain optimal ...

Experimental The library is experimental and minimalistic. The TEMT6000 is a cheap and small analog light sensor. The sensor typically comes on a breakout with only GND, VCC and SIGNAL pins. It is not ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. Last month we saw [Udo]’s blinkenlight shield that can be used as a lin… ...
