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)
