The main process of this research is to display the frequency ranges of input frequency. Any desired input frequency from 10Hz to 30 MHz can be counted and displayed using Peripheral Interfacing Controller (PIC) 16f84A and seven digits of Seven Segment Light Emitting Diodes (LED) display. The input frequency is counted by PIC16F84A and the output from this PIC pins are decoded by analog multiplexer, 4051 Integrated Circuit (IC). Seven digits are displayed by passing seven NPN Bipolar Junction Transistors (BJT), BC547.The main desired output is the high resolution display in MHz range of frequency. Studying the PIC Microcontroller, seven segments LED display and the decoders are included in this research. PIC Assembler Software Techniques are also implemented with this research.
