URBAN S.O.S.
The Urbuan S.O.S. is constructed
using parts made available by the
department of transportation, and at
your local electronics store. The
S.O.S. uses a easy-to-use, open
source microcontroller, called the
Arduino, which is available online.
Notes: There are also large
quantities of barricade lights
available at construction sites
around your city.
