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 ...

[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.

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.

The traffic light server monitoring system uses an Arduino microcontroller to interface with the Xymon server monitoring software. Xymon is an open-source tool that provides real-time monitoring ...

When cities started replacing the old, incandescent bulbs of traffic lights with new LED arrays, it came with all kinds of wonderful upsides. LED arrays last much, much longer than bulbs, which ...

This LED traffic light features LED indicator lamps for high visibility and extreme reliability, explosion proof approval for use in hazardous locations, and a heavy duty design that can stand up ...

As transportation crews replace incandescent light bulbs to the more energy-efficient LED lights, they have found they do not handle snow as well as before.

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.

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.
