Version 1

List of functions

  • 8 doors (4 on each side)
    • 3-color RGB led, digital trigger
    • IR optical barrier, modulated
  • central uC (sets led state, polls optical barriers)
  • USB com chip (translates between serial and USB)

List of complex components

See repository for datasheets.

  • 16x RGB LED
  • 8x IR LED
  • 8x IR phototransistor
  • 4x 959 shift register
  • 1x 555 timer
  • 1x Atmel ATmega168
  • 1x FT232RL USB-to-serial
  • 1x MC33269D-5.0 voltage regulator
  • 1x NDT2955 transistor for power source switching
  • 1x LM358D dual opamp for voltage regulation

Version 2

List of ideas

  • IR transmit/receive with robots in doors using Alex' IRcom library
    • needs analog inputs
  • use LED dimming (PVMs)
  • coded light barriers
  • better LEDs (better spectrum)
