Hi Vik, An input has a 10K pull-up resistor to 5V in it. When nothing is connected to the input the A/D converter will return a value of about 1023 (which represents 5V). If you short the input (make sure it's in passive mode), you will get a value (...) (22 years ago, 11-Apr-03, to lugnet.robotics.rcx.legos)
