On the Subject of Binary LEDs

Binary is a time-honored tradition of communication with tiny blinking lights.

  • Interpret the binary code from the five LEDs. The bit farthest left is the most significant.
  • The code will follow one of the eight numeric sequences below. The sequence oscillates forwards and backwards without repeating the ends.
  • Some numbers in the sequence have a letter underneath them. Cut the wire of the matching color while this part of the sequence is displayed.
  • Only one wire needs to be cut successfully.
