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 ...

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 ...

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 ...

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 ...

The Unihiker K10 is intended to be a small single-board solution for light AI and machine learning tasks. However, you don’t have to use it in that way if you don’t want to. [mircemk] ...
