The Countdown Pedestrian Signal is created from a Dialight 430-6479-001F Countdown Pedestrian Signal Controller, Parallax BASIC Stamp 2, and EFX-TEK RC-4 Relay Control Board.

It simulates the three operating intervals of a pedestrian signal:

• Walk
• Pedestrian Clearance
• Don't Walk

The completed piece measures 18 1/4 inches long, 16 inches high, and 3 3/4 inches deep. It is mounted in a custom wooden frame and plugs into a standard 110VAC US power outlet.
