    AC motor control using 8951 , LCD , any ADC

    hi
    basically i want to make Centrifuge Machine for my FYP, for this i want a circuit diagram , source code of this Keil Uvision software,
    i have to control the AC motor's RPM, also a timer which is set in between 1 to 25 minutes , a beep after the timer is off/stoped , stop option , reset option(for timer) , during motor is Spinning the door will remain closed(it could be done by solonoid switch/mechanism ,but its coding and timing should be include in program/source code), also a message display on LCd that COMPLETE with a beep,
    please do let me help in this its not a big deal simple project but i am weak in programing 8951 also have no idea of using any king of ADC.

    what is the maximum speed you need ?(rpm) you can use mechanical timers and power resister to control speed if you don't know programming
    you can control speed by using light dimmers also
    here is one circuit and program that might help you Downloads / 8051 Projects / Simple Digital Countdown Timer using 7-seg Display : 8051 Microcontroller Projects AVR PIC Projects Tutorials Ebooks Libraries codes

    true is that i don't know the actual speed and RPM of that motor which i'll use in this project , i think it has aprox 10,000-15,000 RPM.
    and i hav to use a program to control the timing and RPM of that because it is in my project requirment,
