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 ...

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 ...

Ambient lighting systems provide accent and subtlety to homes, and are also a favorite of designers of luxury products wishing to highlight their wares. Apple stores, for example, use white light with ...

If you’re going to develop another Arduino-compatible board these days, you might as well take a “kitchen sink” approach. The Smart Citizen Kit piles it on, including Wi-Fi, an SD card slot, and ...

This project shows how to build a light gauge that uses an LED bar graph to show the measured brightness level. The function “gauge()” is a good example of using “if” statements to analyze sensor ...

If you’re anything like me you understand the power of Arduino but are stymied by limitations of education, imagination, or wireless connectivity to implement it into your own life. Thanks to the ...
