    [51] Serial Communication in 8051

    Hi... I want to receive the data from sensor. The output of IR sensor is one bit i.e. either '1' or '0'. If I connect the IR sensor output to RxD pin of 8051 microcontroller, the it will receive only one bit at a time. Then how do I receive the series of 8 bits and save it to the other port. Can...
