| | | No, the RCX knows nothing about the diodes. That is why devices like the light sensor only send a current signal in the range 0 - 0.32mA back to the RCX. This current then creates a voltage drop across the 10k reference resistor with respect to the (...) (23 years ago, 7-May-02, to lugnet.robotics.rcx.legos)

| | | | Ok, I have gotten myself confused again. 0-0.32mA represents a voltage dropbetween 0 - 3.2 volts. Therefore the voltage that the RCX "reads" on theA2D is between 5 - 1.8 volts (1023 - 368 RAW)? To get a reading of 0 (RAW)it seems as though you would (...)
