Editor’s note: Last fall, EEWeb announced its inaugural design contest, sponsored by Arduino and Altium, to develop an imaginative and innovative design project of a motor control system with the ...

A basic Arduino board adds creativity, flexibility, and interactivity to your home lab. It costs little but opens countless ...

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 ...

Depending on how you view them, red light cameras are a great way to get people to drive carefully, or an utter nuisance. We agree with the latter opinion, as does [Dave], so he built a handy little ...

In what follows, we will refer to these collections as “Breadboards,” “Tools,” and “Components” for short. For example, when working with semiconductors such as transistors, diodes (including ...

Light painting is a technique which allows you to “draw” on a photograph by moving a light past the camera during a long exposure shot. While it can be difficult to master, light painting allows for ...
