I am trying to use Java to detect signals from the serial port sent from an IR circuit. When the IR circuit detects an obstacle, it gives an output of 0 volts and otherwise the output is 5 volts. Can I read these voltage differences directly on the PC using Java. Do I need to have a PIC or some other micro controller integrated in the circuit?

Jump to PostI think you will need some kind of driver that will connect to java to get data from a serial port.
