Practical List:

1) Configure timer control registers of 8051 and develop a program to generate given time delay.

2) Port I / O: Use one of the four ports of 8051 for O/P interfaced to eight LED’s. Simulate  binary counter (8 bit) on LED’s

3) Serial I / O: Configure 8051 serial port for asynchronous serial communication with serial port of PC exchange text messages to PC and display on PC screen. Signify end of message by carriage return.

4) Interface 8051 with D/A converter and generate square wave of given frequency on oscilloscope.

5) Interface 8051 with D/A converter and generate triangular wave of given frequency on oscilloscope.

6) Using D/A converter generate sine wave on oscilloscope with the help of lookup table stored in data area of 8051.

7) Interface stepper motor with 8051 and write a program to move the motor through a given angle in clock wise or counter clock wise direction.

8) Generate traffic signal.

9) Temperature controller.

10) Elevator control.
