    Designing tachometer using IR led with 8051

    Hello....

    I want to make project on tachometer using IR leds with AT89S51.

    I want to know how to program time/counter to take measurement in RPM and how do I display on 16x2 LCD

    and how to convert pulses in RPM...what is the formula for it???

    I m programming microcontroller in Assembly
