NextBus is a free internet service using GPS and cellular networks to provide realtime arrival data for over 135 transit agencies in the United States and Canada.
For transit-bound people, the NextBus service is a tremendous convenience. Knowing when a bus is due means less standing out in the rain…one can use that time inside to get a little extra work done, or finish that cup of coffee. In this tutorial we’ll build a handy desk-top or wall-mount countdown display that lets you know when the next bus or train is on the way!
This clock is actively in use in my office 24/7/365. We don’t just make the parts and tutorials, we really do “eat our own dog food.”
