The Arduino Pro Mini used to control the traffic light is not only responsible for playing the tones through a piezo speaker, but as you might expect, for firing off the relays which ultimately ...

Arduino is making "light painting" through the use of LEDs. Learn how this works. Geometric chuck was a particular device that stacked up a number of rotating wheels which vary in speed and their ...

[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. The new … ...

New LED bulbs don't generate the same amount of heat the old incandescent bulbs did, so they don't melt the snow that builds up on traffic lights.

Energy-efficient LED traffic lights may not melt snow, but they do cause accidents.

A blast of winter meant a busy day for city crews Thursday, as they sanded and salted huge swaths of Winnipeg including icy bridges. But now they have to clear snow off traffic signals, too.

Traffic lights using state-of-the-art LED illumination use 90 percent less electricity, offer a much longer service life and are more durable than their incandescent counterparts. Taking advantage ...

Nothing comes close to the awesomeness of this traffic light server monitoring system which has been created using a little Arduino wizardry ...

The global light-emitting diode (LED) traffic signs and signals market size is estimated to grow by USD 487 million from 2024-2028, according to Technavio.

These traffic lights are designed so that the appropriately colored light is only visible by its intended traffic goers. A video showing a LED signal pole in a European town has recently surfaced.
