Connect an led and resistor in series as described below.
1) Connect an led to P0.7 (pin 32 on the 8051) Cathode of led to P0.7.
2) Connect a resistor (330 Ohms) to the aonde of the led
3) Connect other end of resistor to +5vdc
4) Write program as follows:
LOOP:
mov p1,#0ffh ; To configure port for input.
