Frequency Counter using AT89C2051 and LCD

This is a very simple and easy to make Frequency counter project. This project is powered with small AT89C2051 microcontroller with LCD. As we all know frequency of a signal is number of cycle per second. Author made use of this logic to calculate frequency of the input signal. 8051 has two timers, Timer 0 is configured for 1 second delay to sample the input signal and Timer 1 is used as a counter to calculate number of cycles in that 1 second.
