[Rockwell] sent us an update on his traffic light hacking. Dedicated readers will remember seeing this legally attained traffic signal controlled through a parallel port from back in 2005.

After some research, it was determined that it would be relatively simple to have an Arduino convert incoming serial data into a parallel output to the printer. After some testing was performed on ...

and fortunately they are easy to use with our favorite Arduino microcontroller. 8×8 LED Matrix module have many applications in real life, such as various types of electronic display panels. The LED ...

Most ambient lights and sensors are designed to generate light to even out the picture on the front of the panel and reduce any light bleed from the back of an LCD display. This Arduino-powered ...

Arduino enthusiasts or anyone that is looking to learn more about programming an might be interested in a new programmable Arduino-based light board called the Plumduino which has been created by ...

However, this is a great time to look at the difference between series and parallel circuits. A Simple Circuit Just about the simplest circuit you can create uses just one battery and one light bulb.

But none of them come close to the awesomeness of this traffic light server monitoring system, which has been created using a little Arduino wizardry. The monitor has been created to work ...

MIT’s Media Lab is working on a system of information-sharing that can use light-based communication to remind you of an appointment or program an Arduino. The coin-sized Droplet is an ambient ...
