Price On Application

ArcDOS is a countdown timer with traffic light display and sound signal.  It operates via serial output from a Palm to control the ArcDOS hardware system.  The central control consol uses a bi-directional radio link to communicate with up to six display boxes.

The ArcDOS hardware is available as a do it yourself project.  We can provide the software, circuit boards, and pre-programmed microcontrollers along with support and advice.  But be aware that  the system is both large and complex.  It is a project that requires time, money, and some electronics knowledge.
