How to Set Up a Real-Time Traffic Display in the Office (or at Home)
The blog post describes the relatively simple system requirements for a real-time transit display in the office of iStrategyLabs in Washington D.C.: "The first step in building Transit [the display] was choosing the hardware. I decided to go with six LED matrices that provided a similar aesthetic to the real metro signs, one Arduino Mega to power the LEDs, and an Electric Imp to collect the desired data."
After selecting the hardware, all that was left was to decide how much information to display, in this case: "the next four trains arriving at the Dupont Circle metro, how many Capital Bikeshare bikes were available at the Dupont station, and the current temperature for Washington, DC."
Who else wants one?
