Delay using 8051 timer.
The 8051 microcontroller has two independent 16 bit up counting timers
named Timer 0 and Timer 1 and this article is about generating time delays
using the 8051 timers. G
Stepper motor is an electromechanical
device which converts electrical pulses to
discrete mechanical movements.
Stepper motors are available in two
varieties, unipolar or bipolar.

I could get a fair knowledge about micro-controllers in the 3rd lab than the previous ones. But that
could have been done also in previous labs too if I could study more about the micro-controller.
I was able to understan
firstly we gave the hex codes in the book manually to the 8051 development board and observed
the lighting of 5 LED bulbs.
To enter and execute the machine code program,
1. power up the AES-board
2.press PROG key to enter the monitor.
Let the processor to be clocked at frequency 12Mhz
